A posturing and arrogant Q once appeared to Captain Robau to claim that it was more powerful than he was. The Q taunted Robau but Robau did nothing, as he was secure in the knowledge of his own badassery and did not feel the need to show off to lesser lifeforms.
His continued silence only aggravated the Q further, until the Q decided to prove that it was more powerful. Using all of it's power, the Q rose through the planes of existance until it reached the very pinnacle of all existance. At this metaphysical place, one could destroy and remake the entire universe as they saw fit. It appeared as a great platform with five mighty pillars growing out from it.
First, the Q inscribed one of it's trademark symbols into the floor of the platform to prove it had been there. It was about to head back to show Robau until it realised that from here the Q could just destroy the multiverse and kill off Robau for good. It did so.
Galaxies died and universe collapsed until it was just the Q sitting in an empty void. The void was empty...except for Captain Robau.
Astonished, the Q asked how he could have survived. Robau did not say anything. The only thing he did was raise his left hand so it's palm faced the Q.
To it's horror, the Q saw that the symbol that it had left at the pinnacle was inscribed on Robau's palm and that the pinnacle of the universe had been Captain Robau all along.
Captain Robau then wiped it from existance and created a new canon where no Q existed. Fear the power of Robau.
