He’s what? 18? Basically nothing in viltrumite timeframe.
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
He was buffed in the show.
Imo it works better for progression if he barely kept up and was bailed out by his dad last second like in the comic. Really makes the fight feel desperate and brutal.
