When G’iah sneaks a look at some computer files she’s not supposed to see, she discovers a list of creatures that include Groot and Cull Obsidian. Obviously, Groot is everyone’s favorite tree-dwelling alien, and it looks like he left some of his DNA behind on Earth at some point during the events of “Avengers: Infinity War” or “Avengers: Endgame. “.
If you don’t recognize the name Cull Obsidian, aka Black Dwarf, he’s one of the members of the Black Order, the four children of Thanos. Cull Obsidian lost his arm when he was severed by a magic portal during a battle with Doctor Strange, Iron Man, Wong, and Spider-Man on Earth in “Infinity War”.
Also on the list is Extremis, the nanotechnology created by Aldrich Killian in “Iron Man 3”. In the sequel, Extremis technology allowed a person to heal wounds, including full limb regrowth, and it gave them super strength and exothermic ability.
These are all obvious references, but there’s also a deep cut for those keeping track of all the dangling threads of the MCU. Another roster item that G’iah sees is a Frost Beast from Jotunheim, the home of the Frost Giants. If you don’t remember this creature, we saw one in “Thor: The Dark World” sent by the leader of Jotunheim, Laufey, to kill Thor, Loki, Sif, and the Warriors Three. Thor sent that one, but during the climax of “The Dark World”, Convergence portals opened by Malekith resulted in a Frost Beast arriving in London and leaving it behind once all the time. action completed. There was even a post-credits scene that showed the creature still wandering around London.
So why is Gravik keeping track of all that DNA? The answer may lie in the ‘Secret Invasion’ trailer and in Marvel Comics.
