Dylan Porcupine

A porcupine who was also trained by Sally as one of the Substitute Freedom Fighters. He was also the only one of the group able to defeat Sonic when he attacked Knothole while acting under Robotnik's orders while suffering amnesia, accomplishing this by staying quiet and effectively ambushing Sonic instead of making loud, cumbersome attacks like his comrades.

Dylan was later one of three Substitute Freedom Fighters elected to the Council of Acorn. One of the most vocal of the council, he informed Sally and Dimitri the Echidna of the council's decisions regarding sending anyone to Angel Island without getting all the facts about the rebirth of Knuckles the Echidna's arch-nemesis Enerjak.
