Surge is an anthropomorphic tenrec of average height, being about as tall as Sonic the Hedgehog. She possesses mostly bright green fur with a patch of black fur on her face and eyelids and angular blue-green eyes. She has a peach muzzle with a medium-long black nose, upturned sideburns on each side of her head, peach-skinned arms, and several spiky quills that she keeps in a ponytail by a black hairband with six silver studs on top of her head, leaving her quills turned forward. She also has a tiny nub tail split in two, shark teeth, and tall, vertical, flat ears on top of her head.

For attire, she wears two silver earrings on each of her ears, a black shirt with torn-off sleeves, white gloves that possess visible lining with black cuffs that possess six silver studs, a silver ring on each of her index and ring fingers, and yellow, baggy pants with black stripes down the sides that are held up by a black belt with a round, silver belt buckle. Her shoes have yellow flares with double spikes to make them appear that give them a ripped appearance resembling lighting bolts while the back of the shoes is white. Two white straps can be found on the yellow section of the shoes, which also have black toes, black soles with two metal plates embedded, and silver studs on the edges. She is an anthropomorphic tenrec with modified cybernetic enhancements implanted by Dr. Starline and with no memories of her past, and the companion of Kitsunami the Fennec.
