For more characters in Sonic & All-Stars Racing Transformed Deluxe, of course (I know you from Super Smash Bros. 6 on Video Game Fanon Wiki after all).

According to this idea, Opa-Opa (veteran) may change between vehicle forms similarly like in his Fantasy Zone series.
 * 1) Car Form: Regular Opa-Opa, like in Sonic & Sega All-Stars Racing.
 * 2) Plane Form: Opa-Opa gets Big Wings power-up (which obviously makes his wings bigger).
 * 3) Boat: Opa-Opa gets Jet Thrusters power-up (tucking his legs out and having a rocket booster on his back).

For others: Chu-Chus (veteran), Ecco the Dolphin, Altered Beast's Centurion and more when looking at these ones (expect those who you already included).
