Jurgens Thor has some insane showings of endurance. Like taking multiple back-to-back beatdowns from Mangog and still having enough energy to come back, overpower Mangog, and force his hammer down his throat, eviscerating his insides. Otherwise, It's just the standard stuff, galactic teleportation, contending with other heralds, etc. Iirc, I don't think his run introduced any new hax for him either. Unless you count amped states and forms.
Mangog himself can vary in power wildly due to multiple factors, so It's best to just limit him to each iteration's showings.
