On Earth, in his Corporeal vessel, Jason appears to be in his late 20's or early 30's. Of Anglican descent, he has tan skin, short brown hair and brown eyes. He is not overly tall, around 5'10", or a little under two meters. He is hardly an imposing figure, often seeming to blend into the background. Hardly the typical Cherub. He can usually be found wearing nice looking jeans, a loose T-shirt and clean white sneakers.

Jason's Celestial form is somewhat more impressive. In Celestial form he appears as a large, powerful Lion. He is midnight black with silver eyes, mane and claws, and a silver tuft at the end of his tail. He has large black wings tipped with streaks of silver that are normally tucked against his sides but are often unfolded for battle. He has a halo of gold that glitters off his fur as he moves, making his whole body seem to shimmer.
