Don't get me wrong here i mean the Black Beast from BlazBlue ok? good.
Black Raptor is a variation of The Black Beast from BlazBlue (And yes, BlazBlue is part of the Raptor Timeline)
After the Black Beast was defeated before BlazBlue: Calamity Trigger the Black Beast was able to regenerate upon Raptor's shadow. and a year later after BlazBlue: Chronophantasma Extended Raptor and Ragna had to battle Black Raptor, both almost died but they could defeat it.
Later Black Raptor made a alliance with Grimm Raptor that both of them would wipe human, kaiju and faunus kind out of the fase of the Earth
- Black Spiral Beam
Like Grimm Raptor he can shoot a different color beam
