Can you back that up, please? Because in my opinion Zod literally oneshots Thragg.
Invincible was a 30 tonner at the beginning and fighting adult Viltrumites. More powerful ones were +100 tonners, but nothing really implied "incalculable" high herald level strenght. At best top tier Viltrumites are low heralds.
It took 3 Viltrumites to destroy a planet. And they still needed help first in form of someone shooting them the way free into the ground. If that hadn't happened first, they would have probably died upon impact with the planet - according to their own admission.
Does anyone here see Zod crashing into a planet and dying in process? I don't. Mid herald bricks have the durability to survive that.
Invincible's beginning strength shouldn't matter and even then, he was significantly stronger than the thirty ton range. (please log in to view the image) (please log in to view the image)
Hell, before he even started working out, he was explicitly stated/shown to be able to casually bench 400 tons. (please log in to view the image) (please log in to view the image)
As for other Viltrimites, let's look at one of the more noteworthy ones. Here we can see Conquest (who almost killed Invincible) is encased in 400 tons of steel while he heals from his injuries. Pay attention to what's being said here:
Would you look at that? It looks like Thragg actually owned four Viltrumites including Allen and Battle Beast.
Nobody thinks that Thragg would die on impact with a planet because he was leagues above those three. You're also ignoring that he literally tanked the shockwave/explosion of the planet.
Never let anyone else define you. Don't be a jerk just to be a jerk, but if you are expressing your true inner feelings and beliefs, or at least trying to express that inner child, and everyone gets pissed off about it, never NEVER apologize for it. Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
four hundred tons wasn't his upper strength level though. That was his starting strength. Anyway, mark was as strong as Conquest by his second fight with him and Conquest moved four hundred tons in addition to the six miles of rock on top of his head so......yeah.
Also, when Mark beat Conquest for the second time, he was just a little bit under Nolan as far as strength and Nolan, Mark, Thaddeus, Battle Beast, and Omni-boy got absolutely raped by Thragg.
