>>6057256My headcanon was that the fusion canon was the Decepticon heirloom that got passed down leader to leader where their alt mode's incorporate it fully.
Megatron just used it as a normal canon but in alt mode he diverts every last bit of energy to it in tandem, not even allotting for locomotion and instead has to be carried as a weapon himself, which plays into Decepticon's weakness of trust something something metaphor.
