Hes a energin. Basic a being made of energy that prefers to take a physical form.

Before the master crown incident he could do some magic. But the most he could do was teleport and make things float.

But after the master crown incident he was basically dying. the power from the crown burnt up his cells that made energy. Without a gem apple witch has enough energy to last him 12 hours he'll die with out energy as energins use the energy to make their vital organs work.

Now he can control fire make energy spikes and orbs make a tiny black hole and lot of other things that i am not explaining.  If you want to know. Google "magolor star allies"
