Pikachu Bros is a show that branches off from Cartoon House. It is about Kiychu and Bluchu, two special Pikachus who run a hotel.
The Pikachu Bros first appeared early in Cartoon House as two Pikachu with no unique features.
They soon got requests for their own show due to an unusual popularity. In the pilot episode, Kiychu and Bluchu were told apart because Kiychu had a headband reminiscent of the one from an alternate coloring in Smash Bros. They were poor and lived in the Grand Canyon, but by "borrowing" stuff from Reshiram and Zekrom, they eventually built a super popular and expensive hotel that made them extremely rich.
