Knuckles was introduced in "Sonic and Knuckles" as a rival to Sonic who tries to steal his Chaos Emerald. Their rivalry is still there, but now it's more of a friendly rivalry. BEST FRIEND though, I dunno... Tails has been with him since Sonic the Hedgehog 2, and they're really good friends.
No, Tails is. Sonic & Knuckles were rivals at first, but now they're friends, though they still fight occasionally.
