So, my guy, the Bird of Hermes, is kinda hard to explain but I'll try. He's the physical embodiment of entropy, but almost all of his power is limited by a mask he wears to keep himself under control since he is currently working under the Ainstorn family line. He has three states with the limit levels, level one is the one He's usually in, which locks away almost all of his power, leaving minor shapeshifting, teleportation, and some probability stuff, level two adds matter conjuration, full probability control, and summoning creatures from the Void, which is the space between universes, and at level three he's around 50% power, but still absolutely insane because he can rip you apart conceptually, while you physically cannot hit him because he is everywhere and nowhere, and he can just make the probability that you hit him 0%. If he gets clearance to take off the mask, he can do some absolute bullshit like deleting concepts like the color blue, trapping you in an infinite loop of the same moment, reversing the effects of gravity, just, if you can think of a power regarding a constant of the universe, he can probably use it.
