RK Thor: Hey Hulk what's this? You're head? hmm...
Hulk: ......
RK Thor, Hey Hulk what's this? Your arms? hmm....
Hulk....
The Hulk can not win. RK Thor commands metaphysical forces above anything that the Hulk could throw at him. After all of the destruction unleashed on her kingdom Umar was left unharmed. RK Thor was well above Umar, unless someone is suggesting that Umar is as powerful as the Runes? The Hulk lacks even the ability to hit RK Thor tbh.
h1 is wrong once again.
World breaker with versatility of a lantern ring that fuels his anger even more? Idk if any of the spells will work because hulk's healing factor will be through the roof. While the spells work their magic, hulk's healing ability powered by his rage amped by the ring and the gem, it's entirely possible that those spells will be useless.
The hulk won't just be punching him with mangog + level punches but Thor will have to contend with the constant radiation.
