Literally gets dominated by Lucan using one finger.
Then he gets his ass beat by Thula, who has hundreds of years of experience minimum, mind you viltrumites get stronger with age, aaand somehow a pep talk allows him to almost kill her? What? Mind you, in the comics this Thula threw down with Battle Beast and walked away alive
Yeah, Lucan had his guts spilling out and had a giant pointy rock drilled into his internal organs and still managed to get back up and fight. These Viltrumites are incredibly durable.
They are basically super saiyans with wolverine genes. And btw what i say is true because a lot of people dont know or forget that Invincible started as a parody of shonen mangas and Marvel/DC comics overall.
There are like hundreds of CLEAR references to other comics. But when it got too popular, they have to create a unique story since you cant keep going as a parody forever if you wanna have smt for real.
