Pikachu

Pikachu is a contestant, being the third character to ever appear in the series. She has been in every season as well, and she has been able to talk since Brawl of the Plushes Again. She has been a part of the teams Pika Pika Pika, Sweet and Sour, Distant Shore, Team Sword, and UwU. She was also the second person to get implanted by Hug Bear, making her an antagonist during Season 1. In season 2, she received a voice box from Tails, making it so she could speak english. She's had rivalries with many contestants over the seasons, most notably Santa Sackboy and Christmas Mouse. Tails made a machine allowing people to access her mind. Her mind was first used by Rubix Cube, to trap Riku the Cat. In Season 4, Price Tag used it as a base for him and Ryu, setting up the Hug Bear-bring-back-a-tron there, and many more. Price Tag would also use it to easily get the Season 4's main location, to steal the Hug Bear-bring-back-a-tron building guide. Pikachus Older Brother also claims to be her brother, although this isn't true.
