Pichu was one of 14 newcomers added for Super Smash Bros. Melee, and being the pre-evolved form of my main Pikachu, he was something of a secondary main for me.
He was one of several cut from Brawl, and data mining revealed that he was the only veteran not considered for the game, when you consider Toon Link a natural evolution of Young Link. There were many that were glad to be rid of him, given his status as the lowest-ranked on the SSBM tier list and his perception as a "joke" character given that he damaged himself when using electric attacks.
But Pichu had a dedicated fanbase, being one of the cutest Pokemon out there, and have hoped for his return to Smash for a long time. With the Switch out, is this finally the time for Pichu to return to Smash?
