Kit Cosmos is a character in Kirby: Right Back at Ya!. An old veteran of the war against Nightmare Enterprises, he is a Galaxy Soldier who lived a life of solitude after being stranded on an island for an undisclosed reason, and still believed the war was raging on until told otherwise by Kirby and friends. Not necessarily the brightest character but tough as nails despite his age, he is always ready for action, especially against Nightmare Enterprises.
A sound-based enemy that first appeared as a power-up in Kirby's Dream Land, where it allowed Kirby to give off an explosive wave of sound that cleared the screen of enemies when exhaled. In subsequent games, Walky appears as a regular enemy that gives the highly-powerful limited-use Mike Copy Ability, with largely the same effect as the power-up in Kirby's Dream Land. Walky's own attack is also based on sound-emission, but is not nearly as powerful as Kirby's copy ability.
