History
Groot was a member of The Guardians of the Galaxy of Marville which are child versions of the Guardians of the Galaxy. The Guardians of the Galaxy were rivals with the Avengers, the X-Men,[1] and the Inhumans for the attention of the twins Zachary and Zoe. In the end, all four rivals lost to the Brotherhood of Evil Mutants when they convince the twins to join their team.[2] Groot and Rocket visited the Collector to obtain a device from him. He asked to trade it for a "Death Stone". Rocket and Groot assumed this was one of the Infinity Stones and went to search the galaxy. In actuality it was a burger from the local "Infinity Grill" and after they didn't return for days, the Collector went and got it himself.[3]
