Current Thor is afflicted with the Warrior Madness malady, which also makes him bloodlusted enough to spam Godblasts on top of being enhanced x10. Apparently Thorbags claim Thor destroyed a planet when on panel we only see cracks, which could be exaggerated depictions and the statements were from the narrator and could also be HYPERBOLE! Thor may have destroyed a planet with Godblast in the Classic Era, but that cannot be used here because it is as much CIS as Pre-crisis Superman, whom we can't use as a mercy to you Marvel-fanboys.
No BFR.

Superman of Earth Prime: Who soloed the JSL + Thousands of Mid Heralds with his pinky as a boy without his armor. Now he's fully developed and has the Guardian Amp.
