They won't use Starro Tech again (because after a while, using Starro just becomes redundant and annoying). That doesn't mean there aren't other methods of mind control and just as many villains to wield them.

Mad Hatter

Brother Blood (through his own mental powers, apparently, in TT, but he was actually more of a master manipulator in the comics)

Poison Ivy (limited by gender, though)

Queen Bee (mostly limited by gender, definitely limited by proximity)

Psimon (as proved in "Images")

Hugo Strange

And that's only a few of them, most of whom we've all ready seen.
