All-Star Battle R/Koichi Hirose

"A new Echoes! (「新しいエコーズ」)"

Koichi Hirose (広瀬 康一) was confirmed to return for during the game's initial announcement trailer.

His moveset is fundamentally the same as his from, 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 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.

Gameplay
Koichi has 900 health and uses the Stand (スタンド) Battle Style, fighting foes with Echoes. During a fight, he can use various moves from his appearance in Diamond is Unbreakable.

Dialogue
Outside of the All-Star Battle Mode, Koichi has unique dialogue for both his match entrances and victories when facing certain characters.

All-Star Battle Mode
All missions in the All-Star Battle Mode starring Koichi as either the Player or Enemy, in order of appearance.
