Sollux has Psionics, which he can't actually use to control anything. Psionics are essentially stuff like making objects levitate and most notably psychic lasers. Aradia has the ability the summon the dead, and move objects around. Tavros Can control animals. Vriska can control humans/trolls. Gamzee has an ability called Chucklevoodoo that allows him to subliminally affect peoples dreams and manipulate them to his will.

Oh yeah haha, I knew the Gamzee and the dreams thing, I just didn’t know what it was called OTL
I am so quality
