Saying Thor's energy abilities are better than DBZ changes nothing, especially the fact that he's galaxy level, and Buu level plus is universe/reality to multiverse tier. Goku stomps at SSJ1.
Broly destroyed the southern galaxy in less than a day, which was the time it took King Kai to contact and have his dialogue with Goku. Either he is so massively faster than light that he shits in Thor's mouth, wipes his ass, and gets in a stance before Thor can perceive that the fight has started, or he can very near galaxy bust. Leaving two planets and a comet in tact after busting the rest of the galaxy, still qualifies as galaxy busting, because they do kind of, you know, vary in size.
Supreme Kai said Buu screaming would destroy all of creation. As in, all realities, since their were multiple of them established at the time, and all the universes in them. Multiverse. Vegetto punched through his barrier that was even stronger, to stop him. Goku is stronger than Vegetto, as SSJG. He has Goten roast Thor with ki, and they eat him for dinner. GG 👆
What most of you are arguing here, is that somehow, ki strength =/= physical strength, when in fact, everyone else ALSO argues the opposite, as ki is NOT magic. The simple fact lies in the multiple times that characters have tanked galaxy busting ki blasts, and been hurt with punches from stronger characters. Not to mention the fact that MANY characters have batted away similar ki blasts with their bare hands. If someone can use an attack to destroy a galaxy, and someone else can smack that attack away, then that persons hand has galaxy+ durability. It's that simple. 👆
So what if Thor punched Galactus? He also nearly lost to Magneto, and Galactus got pwned by the Fantastic four.
Gogeta being created made a light bigger, and brighter than the universe. Why this is relevant, however, considering we're not talking about characters like Naruto that fall short of planet busting, I'm not sure.
