Jerry is able to 'catch' any ability used against him. When catching an ability, he can either decide to throw the attack back or destroy the attack. This can be used to capture abilities like energy balls, or any other ability used against him. The captured ability can appear as a sphere of unknown energy in the palm of his hand if it is energy-based, but an ability which is not energy-based can still be captured and used if it is offensive. It will not always be visible. The ability is consciously activated, so Jerry can still be harmed by an attack if he doesn't see it coming.
