What better sidekick then Hobbes? He may have been a stuffed tiger to everyone else but to Calvin he was his best friend and the only one that understood him. He stuck with Calvin through all the crazy adventures, sometimes Hobbes was the one coming up with crazier ones. One of the things that makes Calvin and Hobbes so special is the fact that you can't pick who is the sidekick. They both needed each other equally. The below strip really represents the relationship, between the 2 characters. Nothing else truly captures the innocence, life and imagination of a child quite like Bill Watterson (author) did with these two. The companionship of Calvin and Hobbes a boy and his tiger is one of a kind and will never be matched or beaten.
