All-Star Battle R/Robert E. O. Speedwagon

Robert E. O. Speedwagon (ロバート・E・O・スピードワゴン) was confirmed as a playable character alongside Mariah, Pet Shop, and Diego Brando during the Street Date trailer.

His moveset is similar to that of his  appearance, with modifications and new aspects added to better fit him in with ASBR's different style of gameplay.

Having voiced Speedwagon since the Phantom Blood anime adaptation, Yoji Ueda reprises his role in this game as well. Like with the majority of the roster that have returning voice actors from Eyes of Heaven, voicelines for Speedwagon were added and re-recorded.
