Initially tricked by Robotnik into fighting against Sonic, Knuckles soon becomes a useful ally. Taking his place as something of a counterpart to Tails, this echidna brute is a powerful fighter who likes to throw around his spike-laced fists.
Sega added yet another colorful character to its Sonic lineup with the debut of Knuckles the Echidna in 1994's Sonic 3.
