Palladium

Negatus Creatures are very rare magical creatures inhabiting the kingdom of Negatus. Creatures absorb energy, and only a well-executed Enchantix spell can defeat them.

Professor Palladium is a teacher of natural magic, targeted spells and potions at Alpheus. He runs the simulation room. He has the ability to Conjure, teaches at the fairies in Alfea. From Winx

Enchantix is the transformation of fairies. It turns out thanks to self-sacrifice in favor of someone from the fairy's home planet. A fairy with Enchantix magic must be ready to sacrifice herself for the sake of someone who is in danger (enchantix is given when the fairy is on the verge of life and death after being rescued, thanks to which she survives)
