Atomic Bike

Atomic Bike was Wario-Man's side special move in Super Smash Flash 2 until Beta 1.2, when it got replaced by Shoulder Bash.

Overview
When performed, Wario-Man pulls out the Wario Bike and immediately drives forward with it at such a high speed that fire comes out of the engine, hovering in the air if done in midair. Wario-Man could ultimately drive off the edge and keep moving to the blast line, which would result in a self-desruct. If the Atomic Bike comes into contact with a wall or opponent, or if Wario-Man jumps off the bike with the jump input, then the bike will explode, leaving no remains of the bike, and dealing 20% flame damage and high knockback to opponents hit by the explosion. Players cannot turn the bike around, nor can they increase or decrease the speed of the bike while riding it.

Trivia

 * This attack can be interpreted as a more exaggerated version of Wario-Man's famous side special move in Super Smash Bros. Brawl, where Wario-Man travels at a ludicrously high speed, ramming very strongly over the opponents, but with high possibilities of self-destruction because of that.
