once again thinking about my version of Erick where he's an ultrakill prime soul. specifically how he behaves in the fight.
im thinking, does the V2 thing where if you try to get close he backs off but try to get away and he closes in. in close-range he straight up manifests a sword and is very quick with it, at range it's all spells and he levitates around.
at certain health thresholds, he suddenly just, is on top of V1, grabbing the little bastard with a warning showing up on-screen saying something along the lines of "INTRUSION DETECTED"
then you get a short bit of fighting in a random cyber grind arena with a very, computer-y appearance before he gets kicked out and you resume the normal fight - but the arena's changed to be a room or scene from a layer above wherever you last were, like within the span of that short fight he used V1's possessed form to rip his way closer to the surface and towards an escape.
