Red Arcueid

Red Arcueid is an alternate version of Arcueid Brunestud from Melty Blood, a fighting game series based on Tsukihime. Created by Night of Wallachia, this hypothetical Arcueid has ceased restraining her blood lust and has succumbed entirely. As such, she is sadistic and bloodthirsty, presumably possessing several times more power than Arcueid because she is no longer able to suppress herself. However, she only appears in the Melty Blood series and is merely an illusion made by TATARI. Of course, she only has 1/3 of the real Arcueid's power due to the fact that she would be too powerful for him to control at full power.

Her appearance is notably different from Arcueid, sporting large fangs, a slightly inhuman shape, long claws and red eyes as opposed to Arcueid's normal golden eyes. This is similar to the depiction of Arcueid in Tsukihime Prologue from the time she tasted blood for the first time.
