Pichu

Pichu is a Pokémon introduced in the games Pokémon Gold, Silver and Crystal. It is the pre-evolved form of Pikachu, the Pokémon mascot. It has made its only appearance alongside Mario in Super Smash Bros. Melee and Super Smash Bros. Brawl.

Super Smash Bros. Melee
Pichu is a playable fighter in Super Smash Bros. Melee. It is an unlockable character, unlocked by beating Event Match 37: Legendary Pokémon. After beating it, Pichu will appear to challenge the player and, if defeated, becomes a playable fighter. Pichu can also be unlocked by playing 200 or more matches in the VS. mode of the game.

Pichu has a very similar moveset to Pikachu. However, Pichu is a less convenient character, as it is the lightest and it is easily thrown off the stage. Also, all of its electric attacks (including Skull Bash) causes damage to itself. However, due to its small size, and quick nature, Pichu is usually good for fighting larger enemies, whose attacks hit high in the air. Also, it packs more power than Pikachu, namely because the Pichu species in general have a hard time storing their electricity. Therefore, more power is released and they hurt themselves.

As such, Pichu will usually cause a lot of losses to the player when he/she first play as it, but with practice, it can become a dangerous mouse. Additionally, Pichu has two taunts, one for each direction it's facing. In the game, Pichu was voiced by Satomi Koorogi in both English and Japanese, who does its voice in the Pokémon anime.

Super Smash Bros.Brawl
Pichu is one of the few Super Smash Bros. Melee fighters that did not return as a playable character in Super Smash Bros. Brawl. However, the player can get a trophy of Pichu by clearing All-Star Mode without continuing.

Thunder Jolt
Thunder Jolt is one of Pichu's moves used in Super Smash Bros. Melee. To execute this move, the player must simply press the B Button. A blast of electricity will come out from Pichu's cheeks. It will then start passing by the field, until it finally loses all power, or hits someone. If Pichu is standing on a platform when using this attack, it will move underneath the platform, rather than falling. When in the air, doing this attack would create a ball of lightning. This ball of lighting is less accurate, but definitely more powerful. Thunder Jolt will cause 1% of damage on Pichu. When Kirby copies Pichu's powers, he will be able to use Thunder Jolt. However, Kirby will also take 1% damage for using the move.

Skull Bash
Skull Bash is a move that both Pikachu and Pichu know in Super Smash Bros. Melee and Super Smash Bros. Brawl. It is executed by pressing Side + B. Once done, Pichu will pull its head back, and then push forward into the opponent with a headbutt. The player could hold down on the B button to charge the attack. This will make the attack stronger, and will make it more accurate. Sometimes, Pichu will even be able to fly completely across some stages, like Pokémon Stadium or Green Greens. If the player charges the attack to its limit, then Pichu will use the attack automatically. Compared to Pikachu's Skull Bash, Pichu's Skull Bash takes longer to charge up, but can go farther and is stronger at maximum power. Unfortunately, it'll take 1% damage after using the attack.

Pichu never learns this attack in the Pok&#233;mon games, but the move may be a reference to the attack, Headbutt. Also, Luigi can use a similar move, called the Green Missile.

Agility
Agility is one of Pichu's moves in Super Smash Bros. Melee. It was done by pressing Up + B. To use it, the player must tilt the control stick in the direction they want the Pokémon to move. Pichu will move at a very quick speed, which will allow it to get back onto the field when it is thrown off the edge. This, is however, a very hard attack to master. It is similar to Pikachu's Quick Attack. If the player tilts the Control Stick to the side, at just the right time after using the attack, Pichu will do a second jump to the side. It is one of the best third jumps in the game. Unfortunately, the first jump does 1% of damage on Pichu, while the second jump does 3%. Also, it does no damage to opponents and is slower than Pikachu's Quick Attack.

Pichu can't learn this move at all in the Pok&#233;mon games. However, Pikachu and Raichu can. Also, in the games, Pok&#233;mon who use it just gets their speed sharply increased.

Thunder
Thunder is a move used by both Pikachu and Pichu in Super Smash Bros. and Super Smash Bros. Melee games, and returns as one of Pikachu's attacks in Super Smash Bros. Brawl. To perform it, one must press Down + B, which will cause a powerful thunder bolt to drop down onto the screen, in a vertical line from directly above the user. It will fall onto Pichu, and will hurt any player that touches the lightning, or within close range. If the lightning hits Pichu, it'll take 3% damage. Also, if Pichu is jumping when the attack strikes, it will not hit underneath them. It is Pichu's strongest move, in both Super Smash Bros. and the Pokémon series, from which the move is taken.

The difference between Pikachu's Thunder and Pichu's Thunder is that Pichu's can inflict multiple damage to opponents.

Trivia

 * Pichu is the only character from Super Smash Bros. Melee to not have any playable data in Super Smash Bros. Brawl (excluding Young Link who was considered to be replaced by Toon Link).
 * One of its alternate outfits in Super Smash Bros. Melee are a pair of blue goggles. This is later by Pikachu in Super Smash Bros. Brawl.
 * Despite being fast and nimble in Super Smash Bros. Melee, in the Pok&#233;mon RPGs, Pichu's speed stat is actually pretty low.
