>>42562060Came in here to post this. Missingno would be an amazing pick, both as a pokemon rep and as another oddball choice.
Let's see... neutral B is tossing random pokemon themed items which do various amounts of damage. The most damaging is a Rare Candy, which can be picked up afterwards and used as a heal by anyone. Up B is either a vertical Sky Attack or a horizontal Water Gun boost depending on which direction you tilt the stick . Side B is randomly a swipe from a Kabutops claw, a bite from an Aerodactyl skull, or the Lavender Town ghost flying forward as a projectile. Down B is a counter that applies a random status effect to the opponent. Standard attacks are launching various glitchy particle effects from it's body.
I'd want it to have very weird physics. Heavy and slow on the ground, but light and floaty in the air. The hitboxes for itself and it's attacks should be deliberately oddly placed, and sometimes the effects of both taking and giving damage are delayed for a second. Fighting Missingno should always be a bit weird.
As a final smash, the stage is briefly transformed into Glitch City with a lot of moving damage hazards and everyone else's controls are reversed. The normal stage's music plays backwards with a slight static overlay.
