I would like to ask what is the diference between that blast and the one Vegeta used in Buu? It looks quite the same to Nappas attack and Zarbon attack, now for logic we can asume that the attack of Vegeta is stronger than Nappas and Zarbon, but because is no quantification in DBZ, Superman fans would asume that is a weak attack, right? and What About Buu attack that pulverise earth? is weaker than this attack of monarch, right? Shame that Toriyama did not quantify the feats according with the history, since Roshi destroying the moon until the end of Z.
Superman dont lose powers under red sun, Batman discover that his powers remain in his body, only that he lose accessibility to his powers, that makes sense to explain why he has feats under red sun.
