Warning: Spoilers ahead for the latest episode of Secret Invasion!
The Skrulls are planning something sinister. The latest episode of the Disney+ series Secret Invasion contained some cool MCU Easter Eggs, but these references had some chilling implications. To recap what's happening on the show, a Skrull named Gravik is currently using his army to destabilize Earth’s various nations. G’iah is one of Gravik’s lieutenants, but lately she’s begun to question his leadership. She also has reason to believe that Gravik is responsible for her mother’s death.
G’iah decided to do some snooping, and she discovered that Gravik’s scientists were up to something. She then looked through a computer, where she found a listing of cell samples. At first glance, what showed up on the computer screen seemed like cool Easter eggs referencing other MCU projects, but I think there is more to them than meets the eye. First, let’s break down what each of these samples are.
- Groot – This is probably the most recognizable sample on the list. You probably don’t need a reminder, but Groot is the sentient tree from outer space who is part of the Guardians of the Galaxy. Groot spent some time on Earth in Avengers: Infinity War and Avengers: Endgame, which is probably when he left those samples behind.
- Frost Beast – The giant Frost Beast from Jotunheim was last seen in Thor: The Dark World. In fact, this Easter egg technically resolves a plot thread from the film’s post-credits scene. When we last saw the Frost Beast, it was still stranded on Earth, thanks to some inconvenient portals. It was seen chasing some birds, but of course, it had the potential to cause more destruction than that. However, the existence of the cell sample implies that the creature was eventually captured and maybe even dissected.
- Cull Obsidian – The alien brute known as Cull Obsidian was a member of Thanos’ entourage. He was seen in the film Avengers: Infinity War. While battling Earth’s heroes, the sorcerer known as Wong used a portal to sever one of his arms. That arm is pictured on G’iah’s computer screen, so it appears that’s what the Skrulls used to obtain their sample.
- Extremis – Introduced in Iron Man 3, Extremis is a form of genetic manipulation that was meant to augment humans to their “full potential.” However, the process was unstable, and would turn people into human bombs. Aldrich Killian used the procedure to gain powers to battle Iron Man.
How did Gravik obtain these samples? Don’t forget, the Skrulls have infiltrated various government agencies around the planet. The real question is: what is he planning on using them for?
This is just a theory, but I think Gravik is trying to create a Super-Skrull. Introduced in Fantastic Four #18 (1963), Super-Skrull was a soldier for the Skrull empire who was genetically altered to have each of the Fantastic Four’s powers. However, aside from the cameo in Doctor Strange in the Multiverse of Madness, the Fantastic Four haven’t been formally introduced to the MCU yet. Therefore, an MCU version of Super-Skrull would need to pull from a different set of powers. This seems like a good time to note that there are four samples on G’iah’s computer. That number is probably intentional.
Gravik was seen using Groot’s powers in one of the Secret Invasion trailers, so perhaps he’ll be turning himself into Super-Skrull. However, why stop there? If his goal is planetary conquest, he might try to make an entire army of Super-Skrulls. This could also lead to a second Kree-Skrull War.
So maybe it's best to not write these samples off as fan service, because their inclusion here has chilling implications that have the potential to rock the Marvel Cinematic Universe.
