Devin Fermin-Grav is the daughter of Keith Fermin and Gus Grav. She is a Subterra brawler partnered with Rex Vulcan, and is a member of the Vestal Division.

Appearance Edit

Devin is an 8 year old Vestal girl. She has lightly curled blue hair with long bangs. Her eyes are big, round and green.

Personality Edit

The polar opposite of her big brother Derek, Devin is a happy-go-lucky and playful girl. She is easily excited and full of relentless energy, and can easily make friends. Devin can actually be somewhat stubborn, although she is easily swayed due to the fact that she is very gullible and easily manipulated.

She cares deeply for her big brother and her other friends, but especially Derek. She stands up for her friends, no matter if she understands the situation or not - chalk it up to a little girl's naivety.

Despite her young age, Devin is well-versed in the workings of Vestal technology.
