The idea of a Wandering Sentinel was conceived as a way to contrast with villains motivated by revenge, fear and personal motives. This character would feel like they are doing the right thing, despite opposition from the people of Mobius. Over the years, the Wandering Sentinel frequently protected Knuckles the Echidna. He hopes that he can convince Knuckles of his true nature and that the spell that put him here will be made redundant. Until then, he continues to face persecution from the likes of Sonic the Hedgehog.
