‘Guardians of the Galaxy Vol. 2′: Is Baby Groot the Same Person as Big Groot?

“Guardians of the Galaxy Vol. 2” has a great cast, but there’s one clear star: Baby Groot. Voiced by Vin Diesel, the tiny version of the bounty-hunting plant creature and partner of Rocket Raccoon (voiced by Bradley Cooper) is super cute, and Groot has most of the best comedy moments in the movie. Baby Groot resulted from Groot’s heroic sacrifice toward the end of the first “Guardians of the Galaxy.” During that movie, the tree creature used his ability to grow branches to encircle the other Guardians and protect them as the ship they were aboard crashed.
