Mr. Green is the archenemy of the Noid in Yo! Noid, a videogame for the Nintendo Entertainment System. He sent strange creatures to attack the city of New York and according to the mayor, their only hope is the Noid himself so he sets out on a quest to stop him using his yo-yo, pizza crusher and other devices. He commands other creatures that look like him as well as other people and animals.
Mr. Green looks pretty much like the Noid in appearance, he's covered from head to toes in a suit with prominences in the head that resemble rabbit ears; and his eyes, nose, mouth and chin are uncovered. The most notable difference between him and the Noid is that his suit is lime green.
