For real though.
If you want a cool off the wall newcomer.
Wave Racer.
Wave Race is a series that has been on the N64, Gameboy and Gamecube. It's trademark was renewed recently and I got a feeling they may revisit it sometime soon.
Now, people might (rightly) assume that moveset potential is the biggest hurdle. After all, the characters in Wave Race just.... race on jet skis.
But still, I theorycrafed a bit.
Imagine if the Wave Racer is always on their Jet Ski and always has the engine on. Below them is a small puddle of water, this will allow them to move. This could be justified by a special medallion giving them the ability to summon water.
Is that bull****? Yes.
But it's cool though and it solves the issue of them being able to move on land or.... space sometimes.
The moveset proper would involved things like tricks, spins and tackles. Specials could involve small waves of water and even take cues from Jet Kirby for their side special, storing a charge and unleashes it for a huge tackle that sends them to the other parts of the screen. Their overall playstyle could center around their unique movement style where they would trade traction for immense bursts of speed. If a way, they become an opportunist hit and run character.
Just some thoughts. What do you think?
