Pugna
[wiki] rating: 2.0 (winrate: 53% pickrate: 4%)Phantom Lancer
[wiki] rating: 2.0 (winrate: 51% pickrate: 10%)Disruptor
* 
Doppelganger lets Phantom Lancer instantly escape from 
Kinetic Field.
* Doppelganger is one of the most reliable ways to dodge 
Glimpse, other than spell immunity.
* Doppelganger dispels 
Thunder Strike.
Additional:
* Doppelganger is a very reliable tool against Glimpse, enabling him to dodge it consistently.
* Doppelganger also allows Phantom Lancer to escape from Kinetic Field so long as there isn't a Static Storm on top of him.
Medusa
* Phantom Lancer with 
Diffusal Blade will very quickly burn Medusa's mana, making Mana Shield significantly less effective.
* Doppelganger's 1 second invulnerability can be used to dodge Medusa's petrification from Stone Gaze, as well as Mystic Snake.
* Phantom Lancer's illusions outnumber Medusa's targets from Split Shot, likely shielding your team in the process.
Bane
[wiki] rating: 1.6 (winrate: 54% pickrate: 3%)Disruptor
* Heroes that wish to disrupt fights with spell combos or big ultimates are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, 
Enigma, 
Faceless Void, 
Invoker, 
Lich, 
Magnus, 
Mars, 
Medusa, 
Outworld Destroyer, 
Phoenix, 
Puck, 
Queen of Pain, 
Shadow Fiend, 
Treant Protector, 
Underlord, 
Winter Wyvern, 
Witch Doctor, 
Zeus.
Medusa
* Fiend's Grip provides mana drain, which can heavily damage 
Mana Shield and prevent Medusa from using 
Stone Gaze.
* Even if she does use Stone Gaze, Nightmare can buy enough time to protect allies and reset the fight.
Additional:
* His 
Fiend's Grip will leave Medusa defenseless after he's done, if his teammates can provide cover for him or he initiates at the right time by Spell immunity.
Nyx Assassin
[wiki] rating: 1.6 (winrate: 54% pickrate: 7%)Disruptor
* Heroes that can pick you off: 
Clinkz, 
Nyx Assassin, Puck, 
Riki.
Medusa
* With her passive 
Split Shot, Medusa can be easily interrupted by Spiked Carapace during combat, especially during her precious Stone Gaze.
* Mana Burn quickly destroys Mana Shield, especially if Medusa only increases her mana pool by bolstering intelligence (which has the added bonus of increasing Mana Burn's damage).
* Uncontrollable damage from 
Mystic Snake and Split Shot can trigger Spiked Carapace.
* Medusa lacks single target damage, making a Burrowed Nyx Assassin hard to kill.
Additional:
* Level 4 
Mana Burn burns 38,5% of Medusa's mana every 4 seconds if Medusa only increases her mana pool with intelligence. Additionally, 60% of the Mana Burn damage gets mitigated by Mana Shield, burning even more mana.
* Due to the passive nature of Mystic Snake and Split Shot, it can possibly proc Nyx's 
Spiked Carapace if he's within range of Medusa's abilities and isn't invisible.
* Medusa lacks single target damage, making Nyx with 
Aghanim's Scepter extremely hard to deal with if Medusa is the team's main damage source.
Juggernaut
[wiki] rating: 1.6 (winrate: 52% pickrate: 19%)Medusa
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, 
Naga Siren, 
Terrorblade, 
Juggernaut, 
Spectre, 
Slark,
Drow Ranger.
Disruptor
* 
Blade Fury allows Juggernaut to simply move out of Kinetic Field and to dodge Glimpse.
* 
Healing Ward can keep heroes trapped in the Static Storm alive.
* 
Omnislash can be used to dodge Glimpse.
Silencer
[wiki] rating: 1.6 (winrate: 49% pickrate: 5%)Medusa
* Silencer burns easily through her effective hp from Mana Shield, by taking away her int.
* 
Arcane Curse punishes her repeatedly casting Mystic Snake to keep her mana pool high. Can force her to use 
Manta Style before he has cast 
Global Silence and Medusa usually does not want to build 
Black King Bar.
Disruptor
* Heroes with silences : 
Bloodseeker, Riki, 
Silencer.
Riki
[wiki] rating: 1.6 (winrate: 48% pickrate: 5%)Medusa
* He won't be around waiting for Medusa to Stone Gaze and pin him until she bears a true sight.
* With 
Smoke Screen, Riki will silence and catch Medusa in a surprise with high miss chance flushing her from positions easily in team fights.
* He can still deal huge amount of damage through 
Cloak and Dagger via backstabs, drying out Medusa's protection in a whim at random occassions.
Disruptor
* Riki with 
Tricks of the Trade
* Heroes that can dodge Glimpse:
* Puck with 
Phase Shift
* Riki with Tricks of the Trade
* 
Phantom Lancer with Doppelganger

Sleight of Fist and 
Activate Fire Remnant
* 
Chaos Knight with 
Phantasm

Mirror Image
* 
Tusk with 
Snowball
* Juggernaut with Omnislash
* 
Brewmaster with 
Primal Split
* 
Lifestealer with 
Infest
* Phoenix with 
Supernova
Sniper
[wiki] rating: 1.4 (winrate: 49% pickrate: 6%)Disruptor
* Sniper can kill Disruptor while he is trapped by Kinetic Field from a long range.
* Sniper generally stays in the back, making it hard for Disruptor to cast any of his skills on him in lane.
Medusa
* Medusa is a fairly immobile hero that deals damage around her with Split Shot. Sniper should outrange her and should stay out of harm's way from Split Shot.
* More importantly, Sniper should have enough attack range to fire at Medusa during her Stone Gaze without turning to stone, so the ultimate is mostly wasted against him.
Additional:
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Disruptor
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: 
Batrider, Disruptor, 
Pudge, 
Vengeful Spirit
Naga Siren
[wiki] rating: 1.2 (winrate: 54% pickrate: 2%)Medusa
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark,Drow Ranger.

* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova
Arc Warden
[wiki] rating: 1.0 (winrate: 54% pickrate: 4%)Medusa
* Unlike other illusion heroes, 
Tempest Double won't be instantly destroyed by Stone Gaze since it is considered a clone and not an illusion.
* He can use either his own or his double's 
Flux to bypass the spellblock from Linken's Sphere, using the leftover Flux + 
Spark Wraith to slow Medusa's move speed to a crawl.
* Arc Warden has a farming advantage with double 
Hand of Midas, and can generally bully Medusa with other items that benefit from duplication.
Broodmother
[wiki] rating: 1.0 (winrate: 53% pickrate: 2%)Medusa
* Webbed areas can be used to hit and run, covering distance hastily weakening her on the way and initiating ganks.
* Even though Medusa can hunt down Spiderlings easily when given enough range, after an Incapacitating Bite she will get her swarmed in no time.
* Medusa usual do not build a BKB to benefit from Mana Shield fully while Broodmother can fit a Diffusal Blade to burn away mana.
Additional:
* 
Incapacitating Bite will give Medusa a dire time to clear horde of small spiderlings or retaliate Broodmother herself.
* 
Spin Web will allow broodmother to pick her own fights and sometimes slip away to ambush Medusa.
Abaddon
[wiki] rating: 1.0 (winrate: 52% pickrate: 5%)Disruptor
* 
Aphotic Shield dispels Thunder Strike.
* 
Mist Coil can be used to heal an ally trapped by Static Storm-Kinetic Field combo.
* 
Borrowed Time makes Abaddon nearly impossible to gank.
Invoker
[wiki] rating: 1.0 (winrate: 50% pickrate: 16%)Medusa
* 
EMP is a large mana burn nuke which can hit Medusa's Mana shield with enough damage to lose even more mana.
* 
Deafening Blast disarms Medusa's ability to deal pseudo-AOE damage during teamfights.
* 
Cold Snap allows the opposing team to repeatedly stun Medusa in short succession, preventing her from successfully casting her ultimate due to its long cast time.
Additional:
* EMP allows Invoker to burn Medusa's mana to weaken Mana Shield.
* Medusa's lack of mobility makes her easy to kite with Invoker's spells.
Lion
[wiki] rating: 1.0 (winrate: 50% pickrate: 17%)Medusa
* Medusa lacks mobility or escape mechanisms. Earth Spike and Hex can neutralize her strong damage potential and allow for Lion's team to focus her down.
* In addition to easily breaking her commonly bought 
Linken's Sphere with its low cooldown, Mana Drain can quickly drain her Mana Shield, making her far less tanky.
Viper
[wiki] rating: 1.0 (winrate: 47% pickrate: 6%)Disruptor
* 
Corrosive Skin minimizes the damage Viper takes from all of Disruptor's skills.
Rubick
[wiki] rating: 1.0 (winrate: 46% pickrate: 16%)Medusa
* Because of her need to get status items early to tank it up, Rubick can greatly reduce her damage early with Fade Bolt
* Her stationary nature and the slow cast time of her spells makes it easier for Rubick to steal Stone Gaze or Mystic Snake
* Aghanim's Scepter's Mystic Snake is often better used by Rubick than by Medusa
Keeper of the Light
[wiki] rating: 1.0 (winrate: 45% pickrate: 4%)Medusa
* 
Chakra Magic can drain her current mana, draining away her effective health in a sneaky way.
* 
Will-O-Wisp will keep Medusa busy after she got hit by 
Blinding Light.
Clinkz
[wiki] rating: 0.6 (winrate: 53% pickrate: 4%)Disruptor
* Heroes that can pick you off: Clinkz, Nyx Assassin, Puck, Riki.
Chaos Knight
[wiki] rating: 0.6 (winrate: 52% pickrate: 3%)Disruptor
* Chaos Knight with Phantasm
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova
Additional:
* Phantasm removes Glimpse and dispels Thunder Strike. Additionally, the Phantasm illusions make it difficult to use Glimpse and Thunder Strike on the real Chaos Knight.
* Disruptor's lack of mobility, combined with his lack of innate defense, sets him up for a Reality Rift and a beatdown by Chaos Knight and his illusions.
Mirana
[wiki] rating: 0.6 (winrate: 51% pickrate: 16%)Medusa
* Other heroes with mana burning or manipulating abilities will make Medusa much less tanky: 
Lion, 
Mirana, 
Weaver.

[wiki] rating: 0.6 (winrate: 47% pickrate: 4%)Medusa

* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark,Drow Ranger.
Bristleback
[wiki] rating: 0.6 (winrate: 46% pickrate: 8%)Medusa
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: 
Tidehunter, 
Bristleback, 
Slardar.
Kunkka
[wiki] rating: 0.6 (winrate: 44% pickrate: 3%)Disruptor
* X Marks the Spot is a counter to Disruptor's Glimpse, but you need quick reactions to pull it off.
Additional:
* 
X Marks The Spot allows Kunkka or his teammates to fight back under effect of Glimpse.
Ursa
[wiki] rating: 0.4 (winrate: 51% pickrate: 16%)Medusa
* Medusa's tankiness doesn't help her very much against Fury Swipes in long teamfights.
* With no escape mechanism and a slow movement speed, getting jumped on by Ursa usually spells a quick end for Medusa in the early game.
Additional:
* Ursa's status resistance from 
Enrage will ignore Medusa's gaze.
* Ursa can stack damage with 
Fury Swipes easily against her Mana Shield in a prolonged team match.
Disruptor
* Ursa struggles against heroes with strong (and especially undispellable) disables (Disruptor, Puck, 
Shadow Demon, Outworld Destroyer and etc).
Omniknight
[wiki] rating: 0.4 (winrate: 47% pickrate: 1%)Disruptor
* 
Purification allows Omniknight to keep a hero trapped in the Static Storm alive.
Disruptor
* Heroes with large magical AoE damage will fare well against Omniknight: Lich, 
Ancient Apparition, 
Jakiro, Disruptor
Sven
[wiki] rating: -1.0 (winrate: 43% pickrate: 1%)Medusa
* Stone Gaze allows Medusa to easily kite and kill Sven.
* Mystic Snake eats away at Sven's small mana pool.
* Mana Shield negates much of Sven's burst damage.
Doom
[wiki] rating: -1.0 (winrate: 44% pickrate: 2%)Medusa
* Doom does not disable Mana Shield. As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
* Medusa is an ideal Linken's Sphere carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.
Magnus
[wiki] rating: -1.0 (winrate: 44% pickrate: 4%)Disruptor
* Disruptor can disable Magnus's Blink Dagger using Thunder Strike during a considerable duration, disrupting his initiation attempts.
* Glimpse brings Magnus back after he escapes with Skewer and/or Force Staff.
* 
Static Storm if used on a fight can prevent Magnus from using Reverse Polarity after he jumps in.
Meepo
[wiki] rating: -1.0 (winrate: 45% pickrate: 1%)Medusa
* Poof won't damage Medusa and he can Gaze an entire flock of Meepos.
* Mystic Snake will easily become the bane of Meepo early game.
Enchantress
[wiki] rating: -1.0 (winrate: 46% pickrate: 1%)Medusa
* Enchantress often has a small army of neutral creeps, allowing Medusa to hit her with a later bounce of her Mystic Snake.
* Untouchable is ignored by secondary attacks from Split Shot.
Shadow Fiend
[wiki] rating: -1.0 (winrate: 46% pickrate: 18%)Disruptor
* Glimpse and Kinetic Field allows Disruptor to set up some early kills onto Shadow Fiend.
* Static Storm can be used to cancel the cast of Requiem of Souls.
Queen of Pain
[wiki] rating: -1.0 (winrate: 47% pickrate: 9%)Disruptor
* 
Blink and positioning is crucial for Queen of Pain. These factors are heavily countered by a good Glimpse.
* Static Storm is devastating for Queen as she relies heavily on her spells to inflict heavy burst damage.
Additional:
* Thunder Strike gives vision of Queen of Pain when she's trying to escape. When combined with Glimpse, her mobility and hit-and-run style can be negated.
* While in a team fight, Static Storm forces Queen of Pain to only use right-clicks.
* When combined with the Kinetic Field, she can only wait until she respawns.
Spectre
[wiki] rating: -1.0 (winrate: 47% pickrate: 3%)Medusa
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark,Drow Ranger.
Medusa
* Stone Gaze negates Dispersion's damage reduction and allows Medusa to kite Spectre.
* Spectre's small mana pool is depleted quickly by Mystic Snake.
* Split Shot can clear Haunt illusions quickly.
Disruptor
* Disruptor can control where she goes with Kinetic Field and Glimpse. Static Storm shuts her down in teamfights.
Legion Commander
[wiki] rating: -1.0 (winrate: 47% pickrate: 11%)Medusa
* Mana Shield makes Medusa very hard to take down in Duels.
* Stone Gaze stops Legion Commander from Dueling altogether, regardless of who she targets.
Axe
[wiki] rating: -1.0 (winrate: 47% pickrate: 8%)Medusa
* Mystic Snake can harass Axe in lane and drain his small mana pool.
* Mana Shield reduces the effectiveness of Counter Helix.
* Stone Gaze makes it very difficult for Axe to pursue.
Centaur Warrunner
[wiki] rating: -1.0 (winrate: 48% pickrate: 3%)Disruptor
* Kinetic Field and Glimpse can completely negate Stampede.
Earthshaker
[wiki] rating: -1.0 (winrate: 49% pickrate: 12%)Disruptor
* Thunder Strike can be used to cancel Earthshaker's 
Blink Dagger.
* Glimpse brings Earthshaker back after he jumps on Aghanim's Scepter upgraded Enchant Totem.
* Static Storm if used on a fight can prevent Earthshaker from executing his combo after blinking in.
Storm Spirit
[wiki] rating: -1.0 (winrate: 49% pickrate: 12%)Disruptor
* At around the 10-minute mark, Disruptor would normally be level 6 or 7. This means you can have a level 3/4 glimpse along with Static Storm. A high level glimpse is enough to pull Storm back to a Static Storm even after he used 
Ball Lightning due to his limited mana pool at that time.
* Be careful in the late game however, as there is a good chance he will kill you straight-out before Glimpse has finished bringing him back. Therefore Glimpse would simply bring him back to safety after he's murdered you or a teammate. Of course, this is assuming he hasn't silenced you with an item.
Pangolier
[wiki] rating: -1.0 (winrate: 49% pickrate: 12%)Medusa
* Split Shot will keep attacking Pangolier even when he is rolling around.
* Stone Gaze stuns Pangolier during Rolling Thunder, or forces him to roll away.
Necrophos
[wiki] rating: -1.0 (winrate: 50% pickrate: 3%)Medusa
* Mana Shield tanks most of the damage from Reaper's Scythe; with sufficient mana, the kill threshold drops to 15%/17%/19% health (before reductions).
* Heartstopper Aura does not chip away at Medusa's mana, this makes it not a threat as it deals damage based on current health.
* Necrophos has a movement speed equal to Medusa, and is easy to chase down with a slowing item in Medusa's inventory.
Undying
[wiki] rating: -1.0 (winrate: 50% pickrate: 4%)Medusa
* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.
* Mana Shield reduces the impact of Decay and Flesh Golem's Plague Aura.
Monkey King
[wiki] rating: -1.0 (winrate: 50% pickrate: 16%)Disruptor
* Thunder Strike provides vision of Monkey King when he's in the trees. The periodic damage will also keep Monkey King from using Tree Dance if he's on the ground.
* Glimpse pulls Monkey King out of the trees if he attempts to escape using Tree Dance, and can cause Wukong's Command to end prematurely if Monkey King is Glimpsed out of its radius.
* Kinetic Field and Static Storm can be used to hold Monkey King in place and ensure a kill.
Spirit Breaker
[wiki] rating: -1.0 (winrate: 51% pickrate: 8%)Medusa
* If Medusa activates Stone Gaze, the charge will inevitably fail.
* Mana Shield and overall tankiness allows Medusa to easily survive Spirit Breaker's initiation.
Io
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Disruptor
* Glimpse directly negates Relocate.
Additional:
* Disruptor can always Glimpse back Io or his target after he 
Relocated nearby.
* Even better, thanks to the indicator on the ground, you can even preemptively drop Static Storm and Kinetic Field on the spot they will relocate to.
* Thunder Strike and Glimpse are also good tools to bring back an Io that 
Tethered away in the fog of war.
Underlord
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Disruptor
* Glimpse will return Underlord or any of his teammates attempting to escape with Dark Rift if timed correctly.
* Underlord is a slow and low mobility hero, easy to set up Static Storm and Kinetic Field, preventing him from using his abilities as well as preventing him using Dark Rift to escape
Clockwerk
[wiki] rating: -1.0 (winrate: 52% pickrate: 7%)Disruptor
* Glimpse moves Clockwerk away from allies struck by Hookshot, or under attack by Battery Assault.
* Static Storm can turn Power Cogs into Clockwerk's own grave, but 
Blade Mail will also return the damage to Disruptor.
Visage
[wiki] rating: -1.0 (winrate: 54% pickrate: 1%)Medusa
* Summoned gargoyles will give Medusa free target practice.
* Mana Shield will resist Soul Assumption instances without effort.
Lycan
[wiki] rating: -1.0 (winrate: 54% pickrate: 3%)Medusa
* Her Mana Shield is too tough for Lycan to break in.
* Mystic Snake can hit for a massive damage once it spread between his summons.
Additional:
* Can be easily petrified despite his speed.
* Summoned wolves will be targeted by Split Shot or Mystic Snake
Enigma
[wiki] rating: -1.0 (winrate: 55% pickrate: 8%)Medusa
* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating — and landing an effective Black Hole exceedingly difficult.
* Mystic Snake can be potentially detrimental to Enigma's initiation. Getting hit by the latter high-damage bounces (from standing behind his Eidolons or his teammates) can hinder his mana pool, preventing him from executing a strong initiation.
Additional:
* Mana Shield makes Medusa harder to kill with Enigma's Black Hole and Pulse combo.
* Medusa's Split Shot can kill Demonic Conversion creeps easier and Mystic Snake bounces off from them.
* Stone Gaze makes it hard for Enigma to approach Medusa for a Black Hole.
Nature's Prophet
[wiki] rating: -0.6 (winrate: 44% pickrate: 5%)Disruptor
* Heroes with detection: 
Bounty Hunter, Disruptor, 
Razor, Slardar, Spectre, 
Spirit Breaker
Phantom Assassin
[wiki] rating: -0.6 (winrate: 45% pickrate: 16%)Disruptor
* 
Doom, Disruptor with Aghanim's Scepter, and hex abilities all prevent item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility.
Zeus
[wiki] rating: -0.6 (winrate: 46% pickrate: 8%)Disruptor
* As a spellcaster, silences will nullify him entirely. Some notable examples are Death Prophet, Drow Ranger, Bloodseeker, Disruptor and many others.
* 
Doom, as usual, fits this description nicely.
Mars
[wiki] rating: -0.6 (winrate: 48% pickrate: 16%)Medusa
* Medusa's Stone Gaze forces Mars to choose between getting petrified, or turning his vulnerable back on Medusa.
Dark Seer
[wiki] rating: -0.6 (winrate: 51% pickrate: 3%)Disruptor
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as Disruptor's Kinetic Field or Slark's 
Pounce.
Hoodwink
[wiki] rating: -0.6 (winrate: 52% pickrate: 15%)Disruptor
* Heroes that can negate Hoodwink's mobility: 
Kunkka, Disruptor, Mars.
Chen
[wiki] rating: -0.6 (winrate: 52% pickrate: 0%)Medusa
* Heroes with cleave abilities and area of effect damage can make quick work of Chen's converted creeps and at same time gain farm: Magnus, Jakiro, Shadow Fiend, Kunkka, 
Luna, 
Dragon Knight, Medusa, 
Alchemist.
Beastmaster
[wiki] rating: -0.6 (winrate: 53% pickrate: 6%)Medusa
* Heroes with Linken's Sphere as core item: Weaver, 
Morphling, Medusa.
Tusk
[wiki] rating: -0.4 (winrate: 50% pickrate: 13%)Disruptor
* Tusk with Snowball
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova
Disruptor
* Glimpse can return Tusk to where he was after using Snowball.
Tidehunter
[wiki] rating: -0.4 (winrate: 50% pickrate: 10%)Medusa
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter, Bristleback, Slardar.
Disruptor
* In the mid-game, Tidehunter relies on 
Kraken Shell to stay alive and get his 
Ravage off. Apart from Thunder Strike, none of Disruptor's abilities can be dispelled, so it's rather easy to trap him inside Kinetic Field and Static Storm.
* Be mindful, however, that Kraken Shell still makes Tidehunter very tanky, so be sure that you can kill him with your combo or your partners while he is silenced and trapped.
Bloodseeker
[wiki] rating: -0.4 (winrate: 51% pickrate: 4%)Disruptor
* Heroes with silences : Bloodseeker, Riki, Silencer.
Medusa
* Mana Shield makes it very difficult for Bloodseeker to gain his Thirst bonuses.
* Rupture rarely kills Medusa through Mana Shield.
Slark
[wiki] rating: 0.0 (winrate: 48% pickrate: 13%)Medusa
* Medusa cannot chase Slark in any way and has no disable beyond her ultimate, making her unable to stop him getting away and regenerating before coming back to finish her off.
* Essence Shift removes 1 of every attribute, lowering Medusa's mana pool's cap and leaving her much more vulnerable in prolonged fights.
Additional:
* Medusa is especially vulnerable to 
Essence Shift, as both strength and intelligence contribute to her effective HP, while agility contributes to her damage.
* 
Dark Pact when timed right can be used to dispel Stone Gaze right after it petrifies Slark, allowing him to keep attacking Medusa throughout the duration.
Disruptor
* Thunder Strike provides vision on him while Slark is invisible.
* Glimpse's range at lvl 3-4 is more than enough to pull him back to a favorable position for your team to group up and kill him.
* Even though he is capable of picking you off and deal enough damage to kill you, Slark will be literally sticking his neck out, since jumping on Disruptor means being on his battleground.
* AoE silence and the ability to mute Black King Bar is deadly to Slark at all stages of the game.
Additional:
* Static Storm and Kinetic Field locks down Slark, as he cannot use Dark Pact to dispel any disables, or Pounce out while silenced.
* Glimpse puts an end to any attempts at ganking Disruptor or his allies, and also negates Slark's mobility by bringing him back into the fight if he tries to escape with Pounce.
Lifestealer
[wiki] rating: 0.0 (winrate: 48% pickrate: 5%)Disruptor
* 
Rage can be used to escape from a Glimpse and to move out of Kinetic Field.
* Infest allows Lifestealer to dodge Glimpse.
Medusa
* Lifestealer's low mobility makes him easy to kite.
* Stone Gaze pierces Rage, wasting its cooldown and making Lifestealer unable to fight.
Anti-Mage
[wiki] rating: 0.0 (winrate: 49% pickrate: 13%)Medusa
* Anti-Mage easily destroys Mana Shield with Mana Break, especially once he has Manta Style.
* Anti-Mage effectively avoids Stone Gaze with Blink, and can reinitiate after its duration is over.
Additional:
* Anti-Mage's 
Mana Break burns Medusa's mana easily, especially when coupled with a Manta Style.
* Can easily initiate on Medusa with 
Blink, burning her mana or forcing her to use Stone Gaze.
* 
Mana Void is effective against Medusa's big mana pool and mana usage, presenting a huge hazard to Medusa's allies around her since her Mana Shield still gives her some protection if she has mana.
Disruptor
* Glimpse brings Anti-Mage back after he Blinks away.
* Static Storm stops Anti-Mage from Blinking.
Additional:
* Similar to Queen of Pain, Glimpse can disable Blink, negating his mobility.
* However, 
Counterspell can negate a majority of Disruptor's damage, which may require him to have a partner to successfully kill Anti-Mage.
Slardar
[wiki] rating: 0.0 (winrate: 50% pickrate: 5%)Medusa
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter, Bristleback, Slardar.
Medusa
* Medusa cares less than other heroes about armor reduction, since Mana Shield blocks 70% of all damage without taking armor/magic resistance into consideration. This makes 60% of your Corrosive Haze ineffective until Medusa's mana is drained.
Puck
[wiki] rating: 0.0 (winrate: 52% pickrate: 17%)Disruptor
* Puck with Phase Shift
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova
Disruptor
* Riki and Disruptor: Smoke Screen and Static Storm can be thrown wherever Puck used Phase Shift, making Puck an easy target if it doesn't have Blink Dagger or is on cooldown. Puck is also very susceptible to Riki's high attack damage when attacking from the back. Glimpse also prevents Puck from escaping.
Medusa
*
Nether Ward will cause an unfriendly area for Medusa, draining her mana.
Disruptor
*
Nether Ward can do a ton of damage to Disruptor because of his high mana costs.
Life Drain can be used to heal an ally trapped by Static Storm-Kinetic Field combo (if Pugna is not a target).
*
