The Psycho twins

The psycho twins are and artificial intelligence
they were initially made as a training simulation for combat.

They can alter their appearance, gender and overall shape
(humanoid shapes are preferred).
This feature exists to manipulate their opponents
and make a fight more interesting.

There are two levels of difficulty:

(left one) = Level 1
-> simulates a professional criminal

(this make her practically unable to feel emotion
as it would be insufficient)

PERCY

(Right one) = Level 2
-> simulates a mentally unstable
and therefore an unpredictable opponent

(she specializes in human emotion and often uses it
 to manipulate her opponents)
