How do I kill the Cyclops robot knight?

Question

Starting in the third world, there are these robots with one yellow/red eye who open their mouths to shoot homing rockets at you. They appear indestructible. Is there some way to take them out?

Answer 1

Missile Bot's can´t be killed but they can be temporarily deactivated by melee attacks, some weapons, and it's own missile.

The Missile Bot is a creature that can shoot Homing Missiles that kill you. It can be stopped by 2 punches, and certain projectiles (such as grenades).
