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

"It's me, the dastardly Speedwagon! (おれあおせっかい焼きのスピードワゴン！)"

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, 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, voice lines for Speedwagon were added and re-recorded.

Gameplay
Speedwagon has 950 health and uses the Ogre Street Battle Style, which allows him to fight alongside his friends, Tattoo and Kempo Fighter, with the moves available to him varying based on which ally he has active.

Dialogue
Speedwagon's first ten Taunt and Victory Lines are included in his Taunt and Victory Poses respectively, with two lines per pose; the first two poses of each type are unlocked by default, while the other three of each must be purchased for 450 G each. The remaining lines of both types can be purchased as a single set for 300 G. Speedwagon's Tag Lines can be purchased as a set for  140 G.
