Fan Casting Knuckles the Echidna in The Dawn of Sonic the Hedgehog: & Knuckles

Back when he was six years old the Echidnas of Knuckles' tribe were too greedy for power that they accidentally destroyed themselves in their power, and Knuckles has been orphaned ever since. That sent the Master Emerald flying to an unknown location on the island. For a decade, Knuckles has been training himself on Angel Island so he can find the Master Emerald and guard it so it could not do any more harm. But he failed when he let Robotnik trick him, yet he hopes he can make it up by teaming with Sonic against Robotnik and his forces, hence making Team Sonic.
