Pichu (ピチュー, Pichū) is a Pokémon character in Super Smash Bros. Melee. It is unlocked by completing Event Match 37: Legendary Pokémon or by playing 200 vs. matches. Pichu is the "baby" pre-evolution of Pikachu, and in Melee Pichu has a nearly identical moveset, making it a clone.
Pichu is currently ranked 25th in the F tier due to its poor range and that most characters can easily chain throw it despite its small size and its status as the lightest character in the game. It also takes damage from its own electric attacks, hindering its KOing ability, as most of its finishing attacks involve electricity. Pichu does have strengths, such as having a surprisingly good grab game, and Pichu is very quick and most of its attacks have little to no start-up lag. Pichu also has a decent air game and a slew of powerful attacks, some even more powerful than those of its counterpart. Regardless, Pichu suffers from abysmal matchups, and it has the highest amount of very unfavorable matchups of any character in any Smash game, having a total of twelve. By comparison, Kirby, the lowest on the tier list, has seven, and Bowser, the third lowest on the tier list, has six. Furthermore, Pichu has no advantageous matchups, with three being even (against Yoshi, Kirby and Bowser).
To unlock Pichu, players have to complete Event 37: Legendary Pokémon or take part in 200 VS. matches. Upon completing either criterion, the player will fight against Pichu on Pokémon Stadium, with "Battle Theme" playing.
Pichu as a character falls under the archetype of being nimble, yet relatively weak; indeed, while slightly stronger than Pikachu in some cases, it still has some aspects that are faster than Pikachu, such as higher acceleration and a slightly faster falling speed. Due to its high traction and average falling speed, Pichu has a rather short wavedash; low-lag, fast aerials also give Pichu a good SHFFL, identical to Pikachu.
One of Pichu's main advantages is its perhaps surprising power. While its smashes and tilts are all of short range, all are unusually powerful considering Pichu's small frame. Its up smash and forward smash contain incredible power, possibly KOing characters reliably at as little as 70 to 80 percent, while its down smash semi-spikes opponents and has invincibility frame. Pichu's Skull Bash also has surprising power and distance when charged; at full power, it almost guarantees a KO at many percentages, as well as dealing a massive 39% damage. It also makes a good recovery option to boot.
Pichu also has a surprisingly good air and grab games. Pichu has plenty of options in the air, including an up air that can easily continue combos and other aerials that can easily deal damage. Pichu also has good grab game; its forward and back throws can knock opponents off stage or set up combos, while its up and down throws can potentially start chain throws.
Pichu can also easily maneuver around stages, with very low landing lag, a small frame and a rather fast dash, as well as decent jumping power.
Pichu's greatest flaw, however, is the recoil damage it gets from using almost any of its attacks involving electrical hitboxes. In almost all of Pichu's attacks, at least one percent of damage is directly inflicted onto it, and because of Pichu's light weight, it acts as an extreme detriment to its gameplay; for merely recovering, for instance, Pichu gains four percent directly. Due to Pichu's incredibly light weight (the lightest in the game), this can stack up quickly against Pichu, making it more and more vulnerable by merely attacking the foe. As such, Pichu players need to strike a balance between electric and non-electric attacks; Pichu, however, is reliant on electric attacks for most of its KO and comboing moves.
Additionally, Pichu suffers from large range problems. All of its best and most powerful attacks are very close to its body, making it tough for Pichu to KO or inflict damage easily (especially against characters with disjointed hitboxes). Pichu, however, does have access to two projectiles (Thunder Jolt and Thunder), but both cause recoil damage and have little KO potential; Thunder Jolt, however, does force opponents into the air, but Thunder itself only attacks above Pichu. Pichu's grab game is also heavily hampered by its short range, at the third shortest in the game.
Pichu's defence game is also poor, with short tech rolls, rolling dodges, and a slow, short ledge roll, though its shield is rather large, making shield stabbing less of a problem for Pichu. Furthermore, Pichu is also quite vulnerable to combos (some of which are either infinite or zero-death, such as Ganondorf's chain throw), due to suffering from rather high hitstun.

 Tier placement and history
Pichu was always seen as a joke character by the Melee community; from the very beginning, many noted that it was completely outclassed by Pikachu, who was already considered a bad character at the time. With its poor approach coupled with myriad attacks that damaged itself, including its own recovery, as well as its terrible overall reach, extreme light weight, and difficulty in putting pressure on the opponent, many professionals laughed at the prospect of a serious Pichu player. It started out on the first tier list as 25th place, and has since consistently shifted from 25th to 26th and back, competing with Bowser and Kirby for the spot of the worst character in the game. It currently ranks 25th on the tier list, one spot above Kirby, the current "worst character," with many still firmly believing that Pichu is the worst character in the game due to its overall worse matchup spread than either one of its "competitors" for the position. It has made no impact on any significant tournaments for several years, as none of the top 96 placers of any major Melee tournament are dedicated Pichu players, and its only players are currently either inactive or have better characters to choose from.

In Classic Mode, Pichu can appear as an ordinary fighter in one on one battles, as an ally or as an opponent alongside Kirby or Pikachu, as the sole opponent in a multi-character battle or as a metal opponent in the second to last stage.
