Volt Tackle
Volt Tackle is the name of Pikachu's Final Smash in the game Super Smash Bros. Brawl. Once Pikachu has collected the Smash Ball, it will proceed to charge up a massive amount of electricity. Once charged up, it will dash incredibly quickly in any direction the Control Stick/D-pad is pointed. This will send anyone it hits flying in the air. The move can be easily used in mid-air. If the attack is canceled in mid-air, Pikachu will be unable to move.
Origin
Volt Tackle is named after a secret move in the Pokémon Advance games and later that only members of the Pikachu family can learn. This move in Pokémon is a direct reference to the signature move of the titular character of a Genesis game called Pulseman made by Game Freak. The move's look and controls in Brawl are also direct references to the move's look and controls from Pulseman.
Super Smash Bros. Brawl Trophy Information
Pikachu, transformed into a ball of light that can slam into foes. It can also fly to chase down those who try to jump out of range. Sparks get stronger when you press the attack button. However, its increased inertia makes midair movement tough. If you get carried away flying, the effect will end, and you'll destroy yourself. Be careful it doesn't happen to you.
