Scarlet and Violet were first to add "strong" damage animations to every single Pokemon depending on the move, which has gone undocumented for years.
Champions just reuses them for all moves based on damage! Maushold doesn't seem to have a "third" they just updated damage2.
Oh so this means that there's gonna be three tiers of hit animations in Pokemon Champion depending on how much damage they take (Light, Medium, Strong)
Different damage animations were introduced in ScVi but it seems Champions is gonna add brand new "superstrong" hit animations
