Locke the Echidna

Locke the Echidna is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He was the father of Knuckles the Echidna and a prominent member of the Brotherhood of Guardians. A dedicated Guardian, Locke often put the training of his son above the wishes of his wife, Lara-Le, which resulted in their eventual divorce. After Knuckles' training was considered complete, Locke left his son to defend Angel Island alone, while secretly watching him from within the secret base of Haven. Years later, after Haven was discovered by Knuckles, Locke took a more active role in his son's life. When the Brotherhood of Guardians went missing and Knuckles refused to return to Angel Island, Locke took up position of Guardian once more and protected his fellow Echidnas. Locke fell in the line of duty, sacrificing his life to free Knuckles from Doctor Finitevus' hex, enabling Sonic the Hedgehog to defeat Knuckles, who was currently Enerjak, and restore his free will.
