I feel like the more interesting question is which ones could they NOT conquer outside of their verse?
They aren’t that powerful outside of their verse there’s probably like a million
Mario and Luigi pulling out 2 red shells to kill a viltrumite
Arrakis
Cybertron would probably win
Earth in Romeo and Juliet. I just don’t think Montagues’ can keep up with Viltrumites. Don’t get me wrong, it’s a decent fight, but the Viltrumites take it.
I’m seeing a lot of people overestimating the Viltrumites and a few underestimating. Using the comic feat of Nolan, Mark and Thaddeus the average Viltrumite can be scaled at multi continental. Their speed is scaled at MFTL with planetary durability (surviving the destruction of a planet)
Not earth in real life. Because I am here
Viltrum v. Ego. Not sure if it’s fair but definitely interesting.
What about cybertron?
The mha verse
Galvan. Those lil frogs can’t fight back. Enslave azmuth and make ultimate viltrumites on your team.
