Sonic's Drift car is red, so there's no problem there. Also, Vectorman should still be Sega's.
Here are some of my thoughts on potential new characters:
Template: Character - Vehicle - All-Star Move
Jet the Hawk
- Babylon's Treasure
, a green muscle car styled to look like a flying carpet - Awesome Air Rider
: Jet grabs his twin bansho fans and leaps onto his Extreme Gear; when the action button is pressed, Jet spins wildly, spinning out other drivers and reversing their steering controls.
- Shadow Runner
, a midnight blue motorcycle - Kamaitachi Reppa
: Joe hops off of his motorcycle and begins running on foot. At the same time, two other ninja from Musashi's clan leap onto the track nearby him. When the action button is pressed, all three ninja unleash a spinning Sword Beam
that bounces off of the track and other drivers, causing havoc if most of the racers are in a dead heat. At the end of the move, the extra ninja blow themselves up via Mijin, and Musashi returns to his bike.
- Star Chaser
, a tricycle that has been customized with a star motif - Shooting Star
- Ristar grabs a Star Handle and uses it to propel himself into a flying tackle, dubbed the Meteor Strike back in Ristar the game. During this Super Sonic-esque move, many stars trail behind Ristar. When the action button is pressed, one of the stars shoots forward, slowing down rivals for a few seconds so that Ristar can slam into them for the spin out.
- Sludge Clearer
, a heavily miniaturized version of Vectorman's Sludge Barge - Raster Shot
: This is an immediate use All-Star Move where Vectorman briefly transforms into a tank to fire a massive amount of sludge in front of him. This sludge can cause people to spin out when fired, though it stays on the track after use, drastically lowering traction for all racers in the effected area except for the Vectorman who fired the Raster Shot.
Those are all of my ideas for now.
