Not to mention that Chaos King was never depicted destroying a parallel universe.
Death Metal 4. Prime shattered 3 multiverses in a single punch. He is specifically stated to be able to shatter reality with punches.
Greg Pak Interview:
CosmicBookNews: Can you tell us a bit about the Chaos King? With the Silver Surfer and Galactus involved, he must pose a pretty big threat, more so than we have seen of him as Mikaboshi? (Chaos King being Mikaboshi‘s true form finally revealed?) Galactus is said to be from before the Big Bang. Does the Chaos King predate that and is that why Galactus takes notice?Fred Van Lente: Yes, you are correct – According to Japanese mythology, Amatsu-Mikaboshi is the Void that pre-dated all existence. All existence, even the universe that Galactus originates from. In his original, Terran form, he laid waste to Olympus and killed Zeus in the ARES mini-series.
Since then, and his departure from Earth in Secret Invasion, he has taken over the realm of the Skrull gods and has been engorging himself on the pantheons of other alien races – including the Shi’ar, as seen in Assault on New Olympus. So he is more powerful than ever before – arguably, he’s the most dire threat the Marvel Universe has ever faced.
Greg Pak: Most supervillains want to rule the world, or maybe the universe. Not return all existence to the chaos and darkness that existed before creation itself. The Chaos King is a whole new kind of threat.
