kirby: right back at ya
A 2001-2003 anime based on the Kirby series by Studio Sign and Studio Comet (and dubbed by 4Kids). The series takes primary inspiration from Kirby's Adventure, but mixes in elements from other games up to Kirby Air Ride. It was aired as Hoshi no Kirby in Japan.
Several elements from the anime would be incorporated into later games, such as the design of Meta Knight's sword Galaxia, and the hats for several copy abilities (such as Clean) in future games such as Kirby's Return to Dream Land and Kirby: Star Allies.
