Pichu

Using Pichu in a Playthrough

The Pikachu line is usually most useful once it reaches Pikachu or Raichu, as Pichu's low stats and friendship-based evolution make the earliest stage much less practical in ordinary playthroughs. Once developed, the line offers a valuable Electric typing, strong Speed, and reliable offensive pressure against common Water- and Flying-type targets, with Raichu serving as a straightforward fast attacker and Pikachu remaining viable in some games through Light Ball or other special mechanics. In earlier generations, evolving too early could cost Pikachu some level-up options, so the timing of evolution can matter. Standard Raichu is easy to use and efficient, while later variants such as Alolan Raichu add a more distinct offensive identity where available.

Pichu in Competitive Pokémon

The line's competitive history is split across three different identities: Light Ball Pikachu as a fragile but surprisingly powerful attacker, standard Raichu as a fast utility or offensive Pokemon, and Alolan Raichu as the line's most successful modern competitive variant. Smogon material repeatedly treats Light Ball as the item that makes Pikachu competitively relevant at all, while standard Raichu has found roles through Speed, Encore, support tools, and in some doubles formats Fake Out and Lightning Rod utility. Alolan Raichu has been notably stronger, using Surge Surfer under Electric Terrain to become an extremely fast cleaner or revenge killer with potent coverage. Even so, the line is generally constrained by frailty and by the need for either item support, terrain support, or careful positioning to maximize its value.

Pichu in Nuzlockes

In Nuzlockes, the Pikachu line is often valued highly when obtained early because Electric-types are frequently scarce and their offensive matchups are immediately useful. Community Kanto Nuzlocke discussion tends to describe Raichu as a good but somewhat narrow Pokemon: fast, offensively practical, and able to contribute meaningfully with Thunderbolt and status support, but limited in coverage and not especially durable. If the line is obtained starting from Pichu, the friendship evolution requirement and poor early durability make it less reliable at first. Once it reaches Pikachu or Raichu, however, the line usually becomes a strong specialist for Water- and Flying-type matchups and a useful speed-based attacker, provided it is not asked to tank repeated hits.

Pichu is a young electric rodent Pokemon whose cheek pouches can hold only small amounts of electricity. Because it is still immature, it cannot store electricity well and may accidentally discharge power when startled, amused, or otherwise emotionally stimulated. It often shocks itself in the process when electricity leaks from its pouches, and even these accidental jolts are strong enough to shock adult humans. This immaturity with electricity is treated as a defining trait of the species' juvenile stage.
