Her moveset is fundamentally the same as hers from All-Star Battle, with a few tweaks being made to both balance the character and fit her into the overall gameplay tweaks that All-Star Battle R brought.
In the English localization of All-Star Battle R, Ermes's Stand, Kiss, is localized as "Smack", carried on from its first official usage in All-Star Battle.
Replacing Ermes's previous voice actor of Chizu Yonemoto is Mutsumi Tamura, who voices Ermes in the Stone Ocean anime. Because of this, and like the majority of the game's roster, voicelines for Ermes were either added or re-recorded.
Ermes has 1050 health, making her the highest health character in the game. She uses the Stand (スタンド, Sutando) Battle Style, fighting foes with Kiss. During a fight, she can use several different attacks that were featured in Stone Ocean.
The player's Heart Heat Gauge does not fill while their Stand is active.
