I actually really want to see how sakurai would do a modern redesign for Space Harrier in smash
He could straight up take the gundam influence the original Space Harrier had and make him look almost like Char Aznable/Quattro Bajeena
A small Opa Opa could assist him in battle as a reference to its appearance in Zillion
Hes say's "GET READY" in his battle intro and his victory quote is "WELCOME TO MY FANTASY ZONE". Maybe have the dude from Planet Harriers be his echo fighter. His Battle stance has him floating like Dark Samus and he uses his big *** laser gun for most of his attacks.
Maybe he gains coins while playing as him and he can taunt the weponalds shop to appear so he can upgrade his gun to different types of shots
Have his stage have several enemies from space harrier and fantasy zone as bosses like the castlevania stage since they share the same universe along with a space harrier theme remix and other sega arcade game remixes.
would be cool
