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.
also with this he'd be like. almost pinkish-purple body with dark blue-purple accent color
wild head of hair, spiky like a cartoon character being electrocuted but pointed back. eyes that seem to be flowing with electricity out to the sides. hands are fully blue-purple and that blends into a circuitry pattern up his arms.
spell attacks would be like, he swings one arm and an arc appears that hangs in the air and shoots out lightning and projectiles (lightning being a slightly telegraphed hitscan like the electric railcannon and thus coinable)
im also thinking about the possession and climbing up through hell thing. maybe theres an extra UI element on screen during those sections resembling the bit from the intro to the game, displaying:
MOTOR CONTROL FUNCTION: COMPROMISED
OPTICAL FUNCTION: COMPROMISED
EXTERNAL INFLUENCE DETECTED. OBJECTIVE: PURGE
CURRENT STATUS: APPROACHING [LAYER]
