- Released on July 24, 2014.
- Groot is the only hero to have all of his moves named the same(while each one has a different word highlighted.)
- All of Groot's Flora Colossus' moves are named after the only sentence he says,"I Am Groot.".
- He, Black Bolt and Destroyer are the only heroes to have their recruitment dialogues require another hero to talk for them (Groot can talk, but Rocket Raccoon is translating his words).
- His team-up bonus "Dr. Doolittle" is likely a reference to the name of the movie.
