I can be any physical shape I like.

*The cat's shape grows ragged at the edges, then begins to stretch upwards, brightly. It reforms and there is a young man there, an albino. His white hair matches his white shirt and slacks, and his translucently pale skin. The lack of color hits the eye hard, as hard as if he had had an arm missing. All his color seems to be concentrated into his bright green eyes, which are the same eyes as the cat's had been.*

I have many names, but call me Yrael. A pleasure to meet you, Thea.
