Zac vs Ekko Counter Pick

Chronobreak undoes the work. Zac’s pattern is a long Elastic Slingshot, targets held by Stretching Strikes, and health ground down by Unstable Matter; Ekko’s ultimate rewinds him to a healthier position seconds earlier while he is untargetable. Across 481 games on patch 16.13.1, Zac takes 44.5%.

• Damage: Ekko is mixed, which splits Zac’s 112.9 armor and 32 magic resistance at level 18 into two partial answers.
• Body: Zac reaches 2,538 health against 2,338, but 655 against 685 at level 1 means the early gap is thinner than the tank label suggests.
• Mobility: Phase Dive teleports Ekko to his target on the follow-up attack, and Timewinder slows on the return pass.

Both carry a difficulty rating of 8 and both depend on non-instant tools, so the clash is decided by which one gets read first. Z-Drive Resonance pays Ekko bonus magic damage and a burst of speed on every third hit against the same target, which suits a drawn-out fight with a 685-health opponent. Zac’s counter is Cell Division, reabsorbing shed chunks mid-fight and splitting instead of dying when the damage finally lands. Forcing that ultimate out before Ekko’s is available is the only trade that reliably works. Move speed is identical at 340, and Zac carries no resource bar against Ekko’s mana, so repeated attempts cost him only cooldowns while Ekko’s poke has a running price. Ekko’s kit is on the Ekko entry.
