Groot may be a pretty powerful tree, but he’s no match for Thanos. Thanos is physically superior to Groot no matter what the comics may try to imply. Thanos could crush him or use a giant laser to disintegrate Groot. Groot’s healing factor isn’t bad, but it’s simply not good enough to keep him in the fight forever. Thanos wins.
