When you add Diablos into the gate, I think it would be a good idea if you make them a black Diablos because they are just a female in heat
I wasn't planning on addind subspecies (mostly to keep my workload down) but that could work.
Maybe she could turn black when you win the fight and the aphrodisiac kicks in
that could work
Alrighty! I'll remember to do that when I get to Diablos
