8 Villains Who Made Good On Their Second Chance
6. Knuckles - Sonic the Hedgehog
It's basically impossible to write this list without including Knuckles the Echidna, who is pretty much the quintessential example of a video game antagonist who turned to the light side and absolutely made it count.
Knuckles debuted in Sonic the Hedgehog 3 where he was tricked by Dr. Robotnik into taking on Sonic, amid the belief that he was trying to steal the precious Master Emerald.
In follow-up Sonic & Knuckles, after numerous fights with Sonic, Knuckles finally came to realise the truth of Robotnik's deception, that he was in fact the one trying to nick the Master Emerald for himself.
From that point on Knuckles shifts allegiances, helping Sonic infiltrate Robotnik's lair, the Death Egg, and vanquish him.
Knuckles has remained a mainstay ally of Sonic's ever since - long enough in fact that one might almost forget he was ever against Sonic in the first place. He'll never be quite as iconic a bro as Sonic's bestie Tails, but he's not too far off either.
