Character Profile: Master Green

Master Green only appeared in the pilot episode of the anime, the same pilot episode where a girl resembling Tiff, which is her first design, appears (after which she is a friend of Kirby just like she is in the final version). He appeared along with Captain Stitch, Meta Knight, the Ice Dragon, Dark Matter, Efreeti, Blocky, Haboki, Sweet Stuff, and Mr. P. Umpkin. After using his Ice ability to freeze Dark Matter, Kirby proceeded to inhale Master Green and copy his Spark ability and then use it to fry Efreeti, Blocky, Haboki, Sweet Stuff, and Mr. P. Umpkin.

Master Green was originally a mini-boss in Kirby's Dreamland 2 where he would give Kirby the Spark ability when he inhaled him after beating him. Interestingly, Nightmare Enterprises monster Squishy's attacks are based on Master Green's attacks.
