Thorn is a doppelgänger of her mainstream counterpart, albeit with some notable differences. As such, she is a pink-furred anthropomorphic hedgehog with light green eyes and peach skin covering her muzzle, inner ears, and arms.

Rusty looks almost exactly like Amy Rose, with the primary difference being that she has had all of her body and part of her face replaced with robot parts.

Black Rose speaks using stereotypical pirate lingo and greatly enjoys pirating. She is fond of storytelling.
