Darkseid and Grail hiring Giganta to steal Apokoliptian artifacts makes me wonder if eventually, Grail will form a new version of Villainy Inc. to strike back at Diana and possibly the Justice League. If that happens, who would you like to see on the team?
I'd go with:
Grail
Giganta
Cheetah
Dr. Poison
Queen Clea
Dr. Psycho
Angle Man(whose Angler could be from Apokolips)
