Werehog Sonic and Knuckles - Frenemies Forever

They love to hate each other!

In the Sonic the Hedgehog universe, Sonic and Knuckles were initially enemies due to Dr. Robotnik's deception. Robotnik tricked Knuckles into believing Sonic and Tails were trying to steal the Master Emerald, which is crucial for Angel Island's levitation. This led to conflict, but Knuckles eventually realized Robotnik's deceit and joined forces with Sonic to defeat him. While they have a friendly rivalry, they are now generally on good terms and work together.
