As adorable as Baby Groot is, the character presents James Gunn with something of a conundrum. Groot is voiced by actor Vin Diesel, who is known for having a very deep voice. While that works for Adult Groot, it probably wouldnât be the right fit for the smaller version.
But if Groot will still be kicking ass and using his smaller size as a tactical advantage in the name of defeating the villains, then Vin Diesel's booming vocals will be the way to go. Either way, the voice is as important as the decision to keep Groot in his baby faced form.
