Can Pre-retcon Beyonder destroy the Omniverse?

Can Pre-retcon Beyonder destroy the Omniverse, does that mean he can destroy other fictions?

Answer 1: Yes, Beyonder (Pre-Retcon Beyonder or Cosmic Cube Beyonder) can casually destroy an omniverse if he ever whims it, remember the Original Beyonder entire "Multiverse" was compared to an ocean while the Marvelverse was compared to a single droplet of water.

Answer 2: The majority of other fictional verses don't have an omniverse so they are fodders, and won't even stand a single chance against Beyonder and his infinite power and I mean INFINITE.
