Koichi Hirose (広瀬 康一, Hirose Kōichi) was confirmed to return for All-Star Battle R during the game's initial announcement trailer.[1]
His moveset is fundamentally the same as his from All-Star Battle, with a few tweaks being made to both balance the character and fit him into the overall gameplay tweaks that All-Star Battle R brought.
In the English localization of the game, Koichi's Stand, Echoes, is localized as "Reverb", carried on from its All-Star Battle debut.
Replacing Koichi's previous voice actor, Romi Park, is Yuki Kaji, who has voiced him since the Diamond is Unbreakable anime adaptation. Because of this, and like the majority of the game's roster, voicelines for Koichi were either added or re-recorded.
Koichi has 900 health and uses the Stand (スタンド, Sutando) Battle Style, fighting foes with Echoes. During a fight, he can use various moves from his appearance in Diamond is Unbreakable.
The player's health is decreased. The opponent's health continuously refills.
