Wave 1 Avengers Character Updates

Dev Note: Has it been over 2 years already? The Avengers were a powerhouse when Marvel Strike Force released back in 2018, but over time they've lost some of their luster. We want to take this opportunity to tune them to be more in-line with our modern characters. A lot of the Avengers are already situated on powerful teams that we did not want to break up, but we're excited to see what players make of these changes. You'll notice various stat boosts to characters as well as ability modifications!

Captain America

Dev Note: Captain America had his Basic chain updated to standard conventions, always chaining to at least one target at max level. Cap has had a timing issue with his Ultimate, so to address that we reduced the energy cost and gave him Speed Bar to get to his next turn faster. Finally, to cement Cap as the de-facto leader of the Wave 1 Avengers, we significantly increased Cap’s Block chance, gave him a Health increase for his Avenger allies, and he now heals for a small amount when an ally Avenger falls in battle.

Basic - Shield Bash

  • Updated:

    • Attack primary target for 220% damage. Chain to 1-2 adjacent targets for 170% damage. Gain Defense Up for 1 turn.

Ultimate - Shield Throw

  • New Energy Cost: 3/3

  • Updated: Attack primary target for 300% damage + clear 2 positive effects. Chain to 2-3 additional targets for 230% damage + clear 2 positive effects.

    • Gain +20% Max Health. WAVE I - AVENGER allies gain +20% Max Health.

    • In WAR, gain +20% Max Health. WAVE I - AVENGER allies gain +20% Max Health.

Black Widow

Dev Note: We thought it was a missed opportunity that Black Widow and Hawkeye didn't help each other more in battle, so we've made multiple changes to create a better pairing between the two characters. First, they'll gain Assist Now on each other's turns. Black Widow will always chain to 3 additional targets if Hawkeye is her ally, she'll grant him a stack of Deathproof when she enters Stealth.

Base Stats:

  • Health increased by ~10%

  • Damage increased by ~5%

  • Focus increased by ~18%

  • Black Widow now clears a positive effect on her target when she Assists and Counterattacks.

Passive - Saboteur

    • Gain +15% Speed. This is applied after any character has taken an action. On Stealth, gain Offense Up + apply Deathproof to an allied Hawkeye.

  • New:

    • Gain Assist Now on an allied Hawkeye's turn.


Dev Note: Hawkeye saw a number of improvements to his kit. We amped up his Basic attack, granting some more Crit damage to make the extra Crit chance feel better. We fixed the oddity with his Special ability so now all the effects apply to his primary and adjacent targets. His Ultimate always felt like it was missing something, so it now starts with one more energy and will apply Slow in addition to its original effects. Finally, we increased the chance for his Passive to proc to 100% at the max ability level.

Base Stats:

  • Health increased by ~15%

  • Focus increased by ~25%

  • Speed increased from 116 to 131

  • New: Gain Assist Now on an allied Black Widow's turn.


Dev Note: The goal for Hulk continues to be the same: when he hits, it hurts. In order to facilitate him hitting, we gave him more counter on his Special ability. Furthermore, he'll now gain Speed Bar when an enemy attacks his Wave 1 Avenger allies. Finally, we gave Hulk a bit of Resistance while Taunting, as it's always been a little too easy to shut down the big guy.

Base Stats:

  • Health increased by ~10%
