Who Counters Bystander Hwayoung in Epic Seven?

Frieren, Tori, Disciplinary Prefect Aria and other hard counters counter Bystander Hwayoung. Her counter only fires when an ally takes a hit of at least 40% of their max Health, so chip damage, multi-hit pokes, and softer attacks never wake her up, leaving her passive idle.

Avoiding the 40% trigger: Her counter only fires when an ally takes a hit of at least 40% of their max Health, so chip damage, multi-hit pokes, and softer attacks never wake her up, leaving her passive idle. Counter cooldown windows: Her retaliation can only activate once every few turns; once it fires, there is a gap where heavy hits on her team go unanswered and the enemy can push freely. Slow speed and single-target output: She acts late in the turn order and hits one enemy at a time with no AoE, so faster cleave teams can wipe or cripple her side before she ever gets a meaningful swing in. Her own buff immunity: Because she cannot receive buffs at all, allied speed-ups, attack boosts, immunity grants, and protective shields slide off her, so she can't be propped up or shielded the way a normal carry would be.

In current Champion+ RTA, Frieren has one of the strongest records against Bystander Hwayoung (61% win rate over 26,931 games).

Damage-sharing and protection setups: Her main strike and her counter both ignore damage reduction and damage-sharing effects against enemy heroes, so a target hiding behind a guardian's shared-damage link or a survivability buff still eats the full hit. Light-element teams: Her rage strike deals bonus damage specifically to Light enemies, letting her punch through Light bruisers and carries harder than against other elements. Revive-reliant comps: Damage-reduction and damage-share defenses :: Her Sura strike ignores both damage reduction and damage-sharing links against enemy heroes, so a carry hiding behind a guardian's shared-damage tank or a survivability aura still takes the full hit she cannot otherwise be walled out of. Teams that need her allies dead first: She is wired to retaliate the moment a teammate is hit for 40% or more of their max Health, so heavy single hits on her backline trigger a free counterattack instead of being a clean tempo gain for the enemy.
