I have a few angels.

Natali, the half angel who acts as a prison for the most powerful of Archangels, Sailephine

Michael, who's powers are science based, but he has wings and controls all kinds of energy, helped by his longsword which lets him channel that energy (There's actually a second part to that RP set 300 years later, where he's still alive because he can control life energy, and he's placed seals all over his body to limit himself to 1% of his full power because he blew up like a nuke)

Edit: Oh and also 

Phoebe, Archangel of Protection, who sealed away the powers of five demon lords and got herself caught in the seal as well

and

Crystalis, Demon of Light, who isn't really an angel but rather a fusion of Pestis, Demon Lord of destruction and Crystala, elven high wizard. For a while after the fusion, Pestis stayed in control, but Crystala served as his conscience and eventually wore him down before taking full control (Or so it seems, really she just converted him and they fused into one person)
