Pokemon Facts #26 - Raichu

In Pokémon Red and Blue, there is a Scientist at the Pokémon Lab in Cinnabar Island who will trade a Raichu for an Electrode. If the player talks to him after the trade, he will mention that the Raichu evolved, which is not possible. This mistake was due to the original translation of the script of the Japanese Blue (in which this person traded a Graveler for a Kadabra) rather than that of Pokémon Red and Green. This error was corrected in Pokémon FireRed and LeafGreen, as the script was retranslated.

Raichu's FireRed and Sun Pokédex entries reference a 1903 documentary film called Electrocuting an Elephant by Thomas Edison.

Several Pokédex entries claim Raichu can discharge up to 100,000 volts. However, its Stadium entry claims it can only discharge up to 10,000 volts. This is likely a translation error due to the way numbers are read in Japanese, where 100,000 literally reads "ten ten-thousands".

Although Pikachu is the starter of Pokémon Yellow, it is not possible to directly evolve it into Raichu in the game, and must be traded in from Red and Blue. This inability to evolve Pikachu is a reference to Ash's Pikachu in the anime.

Raichu and its pre-evolved form share their category with Rattata, Raticate, Sandshrew, and Sandslash. They are all known as the Mouse Pokémon.

Raichu's number in the National Pokédex and the Alola Pokédex are the same: 026.

Alolan Raichu is the only regional variant Pokémon to have a Z-Move exclusive to it.
