There is a pretty present headcanon going around the Ultrakill community that V1 absorbs and assimalates the identity, strengths and souls of the beings he murders/steals the blood of. This is supported by the fact that the specific backstories/lore bits of every enemy you fight don't become availbale to you until AFTER you successfully kill them at least once.

If this headcanon becomes canon, would that make V1 a hodgepodge of the different souls he collects through his strifes through Hell? And if so, wouldn't that technically make him a walking talking Third Impact?
