Gred

Gred is a Nighlok in a planned Power Rangers Super Samurai Christmas special. He is possibly named for his colors (green and red) and can shape-shift into another's look. He takes the form of Mike in a plan to trick into thinking the real Mike is corrupt so that he is destroyed. However, Mike tricks him into exposing himself, leading him to a powerful blast of the Five-Disc Beetle Cannon, and then taken out for good by the Battlewing Megazord.

Trivia
His Sentai counterpart appeared in a pre-Genta episode, so Antonio may not battle alongside the other rangers.
