Her black knights are in storybrooke. have been since the beginning. We have just never seen them. And i would assume that Regina still has her heart storage facility in her vault, so she has control of them if needed. and while she should probably give them back their hearts, she may also be wise to hold them for now, because of the EQ.

One former villian that I am wondering might return would be King George. He was an ally to Regina in the EF, and the EQ could spring him from whereever the heros are holding him (I don't think he's dead), The only other old villlains that are living are Maleficent and Sydney. i don't see mal joining forces with the EQ, not when she is enjoying time with her daughter. Sydney might try to join up with the EQ, but I doubt it after she burned him with the mess with Ingrid. All of the other old villains are dead (Cora, Greg, Tamara, Pan, Ingrid, Cruella, Hades, Blind Witch, James)    or reformed (Killian, Ursula)
