Groot

If you think being a Groot fan is easy, try explaining to your non-Marvel friends why your favorite character mostly just says 'I am Groot.' In the 'Greatest Fantasy / Sci-Fi Sidekicks of All Time' league, this wooden wonder isn't just a sidekick, he's a cultural icon. Whether he's sacrificing himself for his pals or just dancing in a pot, Groot brings a whole new level to loyalty and cuteness overload. Plus, decoding his three-word vocabulary? That's a fan sport in its own league!
