Valorant: 10 Best Agents To Counter Iso

Iso is one of Valorant’s strongest duelists, built for 1v1 fights and aggressive plays. His Undercut (shield-breaking bullet) weakens enemies before fights, and his Double Tap (kill-activated shield) makes him much harder to take down in gunfights. But the real threat is his ultimate, Contingency, which isolates an enemy into a 1v1 fight, making it dangerous to play alone against him.

To counter Iso effectively, you need agents who can deny his shield, avoid getting isolated, and force him into bad fights. Whether you prefer initiators who disrupt his pushes, sentinels who slow him down, or duelists who can outmaneuver him, the right pick will make dealing with Iso much easier.

In this article, we’ll go over the 10 best agents to counter Iso and shut him down before he takes over the game in Valorant!

#10: Phoenix

Iso’s whole playstyle is about winning 1v1 fights, but Phoenix’s self-healing and utility give him an edge in these duels.

His Blaze (wall) can block Iso’s vision, making it harder for him to land his Undercut (shield-breaking bullet) before a fight. If Iso activates his shield from Double Tap, Phoenix’s Hot Hands (molly) can break it quickly, taking away his advantage.

Most importantly, Phoenix’s Run It Back (ultimate) allows him to engage Iso without risk, making Iso’s Containment (ultimate) much less effective—if Phoenix gets isolated, he can force Iso to waste his ult on his clone.

If you want a duelist that can survive Iso’s aggressive plays, break his shield, and turn fights in his favor, Phoenix is a strong counter.

#9: Cypher

Iso relies on isolating enemies for 1v1 fights, but Cypher’s traps and intel-gathering completely ruin his plans by forcing him to play in the open.

His Trapwires are perfect for stopping Iso’s aggressive pushes, making him an easy target before he can activate his Double Tap shield. If Iso tries to lurk or take solo fights, Cypher’s Spycam ensures that he’s never unseen, making it much harder for him to catch players off guard.

Cypher’s Cyber Cage can also block Iso’s vision, disrupting his aim and forcing him to fight on unfavorable terms. And if Iso uses Contingency (ultimate) to pull an enemy into a 1v1, Cypher’s Neural Theft (ultimate) can reveal his location, giving teammates a chance to react immediately.

If you want a sentinel that can track Iso, deny him free fights, and stop him from catching teammates alone, Cypher is a great counter.

#8: Fade

Iso thrives in 1v1 fights, but Fade’s recon and crowd control abilities make it much harder for him to take clean duels.

Her Haunt (recon) can reveal Iso’s position, making it easier to pre-fire him before he can activate his Double Tap (shield). If Iso tries to lurk or isolate enemies, Fade’s Prowlers can force him out of hiding, making his aggressive plays much riskier.

Her Seize (tether) is especially strong against Iso because it traps him in place, stopping him from escaping or repositioning after activating his shield. If Iso uses Contingency (ultimate) to isolate a teammate, Fade’s Nightfall (ultimate) can deafen and track him, making it harder for him to win his 1v1 fight.

If you want an initiator that can reveal Iso’s location, control his movement, and weaken him before he can engage, Fade is a strong counter.

#7: Raze

Iso relies on winning direct gunfights, but Raze’s explosive playstyle makes it difficult for him to take clean fights.

Her Boom Bot is great for scouting Iso’s position, forcing him to reveal himself before he can set up his Double Tap (shield). If he does activate his shield, Raze’s Paint Shells (nade) can break it instantly, removing his advantage in fights.

Raze’s Blast Packs (satchels) allow her to outmaneuver Iso, making it harder for him to land shots. If Iso uses Contingency (ultimate) to isolate a teammate, Raze’s Showstopper (ultimate) can shut him down before he even has a chance to finish the fight.

If you want a duelist that can pressure Iso, break his defenses, and deny him space to play comfortably, Raze is one of the best counters.

#6: Sage

Iso thrives on fast 1v1 duels, but Sage’s healing, slows, and wall can completely ruin his momentum and make it much harder for him to secure kills.

Her Slow Orbs are perfect for stopping Iso’s aggressive pushes, forcing him to move slowly and making him an easy target before he can activate Double Tap (shield). If Iso tries to isolate enemies, Sage’s Barrier Orb (wall) can block him off, denying him access to the fight entirely.

Most importantly, Sage’s Healing Orb completely counters Iso’s chip damage—if he lands a few shots but doesn’t secure the kill, she can heal teammates back to full HP, making his effort useless. And if Iso manages to take out a key player, Sage’s Resurrection (ultimate) can bring them back, negating his impact.

If you want a sentinel that can slow Iso down, out-heal his damage, and deny him the fights he wants, Sage is a great counter.

#5: Breach

Iso relies on quick gunfights and clean 1v1s, but Breach’s crowd control completely throws off his timing and aim, making it hard for him to take fights on his terms.

His Fault Line (stun) is perfect for hitting Iso before he can activate his Double Tap (shield), forcing him into an unfavorable fight. If Iso tries to push aggressively, Aftershock (molly) can force him out of position or break his shield before he engages.

Breach’s Flashpoint (flash) is also a great tool to counter Iso’s entries, especially if he’s trying to use Contingency (ultimate) to isolate a teammate. A well-timed flash can completely blind him, making it easier to win the fight. And if Iso sets up aggressively in a site, Breach’s Rolling Thunder (ultimate) can clear him out and force him to reposition, making his duelist playstyle much less effective.

If you want an initiator that can stop Iso’s momentum, force him into bad fights, and completely disrupt his aim, Breach is a strong counter.

#4: KAY/O

Iso depends on his utility to win duels, but KAY/O’s suppression completely disables his entire kit, forcing him to rely only on gunplay.

His ZERO/POINT (knife) can suppress Iso, preventing him from using Double Tap (shield) and Undercut (shield-breaking bullet), making him much easier to take down in a fight. If Iso tries to isolate a teammate with Contingency (ultimate), KAY/O’s NULL/CMD (ultimate) can suppress him mid-fight, stopping him from using his shield advantage.

KAY/O’s FRAG/MENT (molly) is also perfect for forcing Iso out of aggressive positions, making it harder for him to take early fights. His FLASH/DRIVE (flash) can blind Iso before he pushes in, completely ruining his entry attempt.

If you want an initiator that can turn Iso into a regular gunfighter, shut down his abilities, and deny him clean 1v1s, KAY/O is one of the best counters.

#3: Viper

Iso excels in direct gunfights, but Viper’s decay mechanics and vision control make it much harder for him to take clean duels.

Her Toxic Screen (wall) and Poison Cloud (smoke) force Iso to push through decay damage, making him significantly weaker before he even takes a fight. If he tries to engage with Double Tap (shield active), Viper’s Snake Bite (molly) can break his shield instantly, leaving him exposed.

Viper’s Viper’s Pit (ultimate) is also a nightmare for Iso. Since he relies on visibility and quick engagements, fighting inside Viper’s Pit puts him at a huge disadvantage, forcing him into unfavorable fights where he can’t rely on his aim alone.

If you want a controller that can weaken Iso, deny him clear sightlines, and force him to fight on your terms, Viper is a top-tier counter.

#2: Sova

Iso thrives on isolating enemies and taking 1v1 fights, but Sova’s recon abilities make it nearly impossible for him to stay hidden or take clean duels.

His Recon Bolt can reveal Iso’s location before he engages, making it much easier to pre-fire him and deny his Double Tap (shield activation). If Iso tries to lurk or take solo fights, Owl Drone can tag him, forcing him to reposition and making him an easier target.

Sova’s Shock Darts are also perfect for breaking Iso’s shield before he pushes, taking away his advantage in fights. If Iso uses Contingency (ultimate) to pull a teammate into a 1v1, Sova’s Hunter’s Fury (ultimate) can interrupt the fight and force Iso to dodge instead of focusing on the duel.

If you want an initiator that can track Iso, deny his duels, and weaken him before he even takes a fight, Sova is one of the best counters.

#1: Killjoy

Iso relies on taking isolated fights, but Killjoy’s utility makes it nearly impossible for him to engage without consequences.

Her Turret is perfect for stopping Iso’s aggressive pushes, tagging him before he can activate his Double Tap (shield) and forcing him to take damage before a fight even starts. If Iso tries to lurk and catch enemies alone, Killjoy’s Alarmbot can track him, making it much harder for him to find an easy 1v1.

Killjoy’s Nanoswarm (mollies) can deny Iso space, stopping him from taking control of key areas and forcing him out of cover. If Iso uses Contingency (ultimate) to isolate a teammate, Killjoy’s Lockdown (ultimate) can force him to retreat, ruining his momentum and making him an easy target.

If you want a sentinel that can completely shut down Iso’s plays, force him into bad fights, and make it difficult for him to take fair duels, Killjoy is the best counter.
