Assist Trophy:
Space Harrier (SEGA Arcade Series/Others)
When summoned, he could fly above stage, in Background or on stage while mid-air and he shoots at Players from his cannon that gives spamming normal Damage along with Reticle showing where he Aims. He also Dashes at enemies occasionally with great Force that knockbacks the opponents.
Also, he acts like in his OG games during his Assist Role, but his design is based on Ken Sugemori's Artwork.
He can't be KOed or Harmed.
I nominate Space Harrier, because he could represent SEGA Arcade properties like Space Harrier, OutRun, Hang-On or After Burner itself. He could be fun Assist in this game, since we never had a Guy who shoots while flying. He could be interesting pick for Game as Assist Trophy since he doesn't do anything except Flying and Shooting in his games and in this game as Assist Trophy.
