I believe that's the Tomodachi stage, so it seems AT is far more likely.
"Tell them to shut up and have some faith in me." - dead flashback guySakurai doesn't use the words "assist trophy", but his purpose as described in the additional comment makes it clear that he is one. I remember a really early leak (as in, just after Uprising released) that touted this guy as a playable character, and that's the only reason I know of his existence.
Pretty nice and unique assist, based on the description. Also really obscure, which is kinda cool.
What is a fandom? A miserable little pile of flame wars! 3DS FC: 0387-9377-7408 PSN ID: Raven King SageI've never heard of the character, but I'm aware of his game thanks to Rockman 4 Minus ∞ using this theme from that game
for Toad Man's stage.
I'd say Goemon, because that would be totally awesome, but he's not obscure at all in Japan. So I'll just go with S(u)kapon.
"What's out there? What's waiting for me?"I'd love Sakurai forever if he included the Urban Champion as a Shotoclone, if only for the reference of his game being, if just barely, a fighting game.
I sure said that!Yeah, well, Dragon Quest is primitive by modern RPG standards. Dune II is very clunky by modern RTS standards. Wolfenstein 3D plays very differently from modern FPS games. And so on.
"What's out there? What's waiting for me?"

My choices would be Isaac, Takamaru, and Ray MK III.
