Lightning breath - Monstrox is able to release his lightning from his mouth when he is in his book form.
Reanimation - By striking stone statues, Monstrox is able to bring the stone to life, imbued with evil magic. He can also reanimate Stone Monsters that have been petrified by Nexo Powers.
Transformation - Monstrox was able to transform Jestro into an electricity being, changing his outfit and making him want to be evil again.

Electric strike - Monstrox typically used his lightning to get Roberto Arnoldi to start working by making him feel pain.
Fire lightning - After obtaining four Forbidden Powers, Monstrox grew massive in size and used the Power of Blazing Burn to make his lightning set anything on fire.
