Snake is a minor character. He is a former MVP but has slowly left Nintendo after his rejection from Super Smash Bros. for WiiU and 3DS. He took a greater role as one of Kirby's daddy's in earlier episodes, but after Kirby went on for a more mature route, Snake decided it was his time to head back to Konami.
Snake is one of the oldest characters in the episodes. He seems to be more mature than a lot of the other characters. On his returns to Nintendo, he seems to be a bit depressed, which many suspect is a result of his removal from the Smash Bros series. However, Snake is seen to still care much for Nintendo despite his rejection, and has been seen as a savior who comes and goes.
