Cyrax

Cyrax

He is the final boss of the game who appears when Presto is attempting to hatch from his egg. You must defend all the pets (excluding Angie, Presto, and the bonus pets) from Cyrax and the aliens in the boss round. Cyrax doesn't eat the pets, but spawn baby Sylvs which can be destroyed with one laser shot. He is said to be insanely hard to kill, but there is a way to beat him easily.
