Prove me wrong. I'm a lore expert on Destiny, so odds are I can refute any argument you provide that favors Destiny. Vegeta and Goku would beat the entire Destiny universe in a fight.
Lets also assume they know the mechanics for the VoG and Crota's End.

If anyone got close to taking them down (which within the destiny universe would never happen...) Gogeta would then take over ;)
