Trivia[]
Iceman
's Stun removal does not count as an Immunity or a Purify.- Paralyze was originally a variation of Stun unique to
Gambit
and
Spider-Gwen
, that also reduced Power Rate and Regeneration Rate. This Debuff was retired in November 2020 after Gambit's rework, as both Champions' Paralyze was replaced with a regular Stun. - Both Sleep and Striker Opening function similarly to Stun, however they do not count as Stun effects and bypass Stun Immunity.
- To this date, no Champion is fully immune to Stun.
