Backstory
Codexhak wanted to attack the monkeys from MEMIOR so he created C.O.D.E.X.H.A.K. and sent some Aurae Bloons to steal some weapons from the monkeys. Coincidently they all took a ray gun and Codexhak attached the ray guns to C.O.D.E.X.H.A.K. and programmed it to shoot the ray guns accuratly. Codexhak released the C.O.D.E.X.H.A.K. the next time the monkeys came to protect Blotonium Lab. It destroyed all but 1 monkey and it ran away to tell other monkeys. Codexhak boarded C.O.D.E.X.H.A.K. then went to invade Monkey Lane.
