Yuri Lowell is tall and lean, usually seen wearing black with his shirt open to his navel. He favors a sword, which he carries on his wrist instead of on a belt. He has long black hair, usually worn down, and wearing a chunky gold bracelet with a red gem inset in it.

Yuri is a laidback person, whose life philosophy strays toward live and let live, as long as you aren't hurting others. If he sees someone in danger, or being abused by someone, he doesn't hesitate to step in, willing to put his life on the line in the name of fairness.

In Folkmore, Yuri's a familiar who is able to transform into a black house cat with ease, and other varieties of cat with a little more effort. In his human form, he retains black cat ears and a cat tail.

Through his soulmate bond with Flynn, his eyes are a blueish-grey.
