I don't think I've ever even heard of Kracko until either the Kirby Of The Stars anime adaptation, or Kirby Of The Stars: The Tale Of The Fountain Of Dreams Deluxe since he didn't appear in Kirby Of The Stars: The Crystal Shards--which also my very first Kirby game, I believe. It's really amazing just how much this iconic boss has evolved since the original Kirby Of The Stars on the Game Boy in 1992! Even more amazing is that Kirby's Air Ride even had a fully 3D model of Kracko 11 years before appearing in a main series title, Kirby Of The Stars: Triple Deluxe! I look forward to seeing how he'll appear, and what his attacks will be in upcoming years! :D
