The fight is not as you may expect

hmmm
absolute solver can produce blood, but cyn is mostly oil
and cyn can do some hard damage

BUT

V1's coins can target her core

Or also the fact V1 goes way faster than Cyn and that a few railcoining attacks could be enough

V1

cyn would die after two ultraricoshots

Either Cyn gets blasted into tiny metal chunks by a coin or V1 gets completely atomized by a NULL

Fun fact: V1 can tank black holes without much issues
