Thrash the Tasmanian Devil

Thrash is a sentient Tasmanian Devil and the newest member of the Downunda Freedom Fighters who joined sometime after Bill's departure from the group. Thrash appeared alongside the other Downunda Freedom Fighters and helped fend off the Wing Dingoes, who were attacking the Chaotix. (SU: #11) He is shown with great strength and the power of his scream can blast away enemies.

Before Joining the Downunda Freedom Fighters
Little is known about Thrash's past, but Dr. Finitevus seemed to have knowledge of it, stating that Thrash was the remainder of a failed Echidna experiment involving Tasmanian Devils, with Thrash himself being the poorest of them. Little is known after that, except Thrash set about on his own "quest," but achieved little, and decided to join the Downunda Freedom Fighters to "bust up a few heads for a good cause." (SU: #11)

Battling the Dark Egg Legion
Thrash and the other Downunda Freedom Fighters helped fend off a group of Wing Dingoes, who were attacking the Chaotix under the orders of the Dark Egg Legion as part of their assault on Angel Island. He explained that he joined the Downunda Freedom Fighters because his own quest hadn't been working out; what exactly he had been trying to acheive goes unmentioned. He and the Downunda Freedom Fighters took Dr. Finitevus with them under the appearance of working together while secretly planning to eliminate the mad doctor; Thrash made the first move, but Finitevus taunted him, causing him to lose his temper and give the doctor a chance to retaliate. Finitevus was soon joined by Bill's troops, and Thrash and the others were captured. (SU: #11)

After Thrash and the others were released by Bill, who explained how he was forced to lead the Downunda Dark Egg Legion, Thrash led the attack against the Platypus Legion. After routing their forces and causing them to retreat, he informed his team that he would be departing to continue his own quest. (SU: #12)

Personality
Thrash seems to have a profound dislike of Echidnas and while it is uncertain why, it may have something to do with Dr. Finitevus referring to him as a "failed experiment."

Background Information

 * Writer Ian Flynn revealed on his forum that he created Thrash's concept design off a videogame glitch from the SEGA game Sonic & Knuckles, which had a character sprite resembling a weird purple hedgehog/echidna mix as the player attempted to switch characters.
