Cheerful, deterministic, cutesy and bite-sized video game protagonists who are surprisingly pretty strong, having faced demons and gods alike before. They come from extraterrestrial worlds (Craftworld and Popstar) and travel the world and to other planets using their incredibly quick vehicle (the Warp Star and/or Starship for Kirby and the Pod for Sackboy), going on many adventures and meeting a miriad of friends. One of these people was an antagonist who stole from people, but later were redeemed in some way and became friends with our protagonists (King Dedede and the Collector). They have also once faced off against a mischievous jester looking to spread chaos (Marx and Vex), and a backstabber with their own ships who seeked the power of great artifacts who also became redeemed (Magolor and Newton).

Connections so far, haven't fully realized them and they might need polishing if I see anything wrong with them.
