mark was getting clobbered by fucking maulers 3 episodes ago now he’s able to beat a full grown soldier viltrumite that’s been conquering worlds for millennia just because he “stopped holding back”. Even Nolan who got hospitalized by the guardians while soloing them, only suffered a cut on his head fighting THREE viltrumites!!! Just makes them look weak in comparison. I feel like they shouldn’t even have any chance winning that battle at all, not alone surviving in better condition than against way weaker foes
The real-world issue is cells don’t really have a “damaged but not dead” state because they are to fragile. In-world issue being that we clearly see cells getting destroyed (that’s what wounds are) and we even see viltrumites getting hurt and killed by regular weapons. So blunt force can totally kill them.
