>>6129682As it consumes all space on your hand, the parasite reaches the head and spine, with full access to your grey matter and spinal cords. What happens after is hard to discern, for your sense of touch vanishes, and the eyesight grows blurrier, a side-effect of a nervous system experiencing some "re-arrangements".
Your wounds are healed at a moment's notice - the hole filled with its biomass, the bone popped back in place, and the missing chunks of your brain being gently piloted by the pseudopod, allowing for greater control over your body. There was no time to study your biology and perfectly re-create you, as even in your poor condition, you could hear steps growing behind you. Desperate vultures looking to claim the 'loot' from that truck, no doubt.
But that didn't matter. The symbiosis, as imperfect as it was, was complete. As your passenger nudged you into doing so, you could stand again to greet incoming danger at full height. Two extra inches from your standard, your nails sharpened into claws and your mouth turned into a beast's maw ready to bite into junk metal.
The chance to glance at your horrifying transformation is missed as you see brightly glowing eyes gaze at you, all three of them, with a rifle of some kind pointing in your direction. Psycho, confused by the sighting, only gets a single line out of his mouth before you lunge at him, driven nothing but by your new goal: Revenge.
"What the *fuck* are you. . .!?"
