>Knuckles is not a friendly rival for Sonic since they are not friends.
False.

"Friendly Rival" is literally how Knuckles has always been described, and Sonic Advance 3 is showcasing that specific concept.

According to Sonic Channel:
>They’re rivals, they’re fighting buddies… In the sense of a relationship that “requires no holding back,” it may be as close as the one with Tails.
