Kirby: Right Back at Ya! anime
Kirby: Janice (Yes, I know they're different genders and all, but Janice's slightly ditzy and carefree additude reminds me of Kirby)
Tiff: Skeeter (Skeeter seems like the girl that's tough, but is also very protective)
Tuff: Scooter (If you have Skeeter as Tiff, you have to have Scooter as Tiff's brother, Tuff)
King DeDeDe: Dr. Teeth (They're both overweight, and they are both funny!)
Escargoon: Beaker (Both are hapless lackeys that serve as targets and are really kind, plus are the smart ones)
Meta Knight: Zoot (Both are very mysterious, with little known about them)
Sir Ebrum: Sam the Eagle (Both are serious, and classy)
Lady Like: Miss Piggy (Both are fashionable)
