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 countershading on her face and eyelids and angular teal 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 a sextet of silver studs atop her head, leaving her quills turned forward. She also has a tiny nub tail split in two, sharp teeth and tall, vertical and flat ears atop her head.[14]

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 a sextet of silver studs, a silver ring on each of her index and ring fingers and yellow and baggy pants with black stripes down the sides that are held up by a black belt with a round and 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. A pair of white straps can be found on the yellow section of the shoes, which also have black toes, black soles with a pair of metal plates embedded and silver studs on the edges.[14]

In addition to her normal attire, she also wears bonus attires:

• While she was undergoing Starline's hypnosis, she wore a light blue hospital gown, no shoes or gloves and her hair was undone

• During the Sweepstakes competition, Surge wore a yellow jacket, similar to her pants, a black bodysuit, the same as her black shirt, yellow shoes with white stripes and yellow shades over head and eyes.
