i've never been the biggest troll guy personally, but i dabble from time to time. my most recent one is this guy, a riff on batman:

who i created in a brief youtube video a number of years back, right here: https://www.youtube.com/watch?v=AVKihiEYugw

i've also got these three, but they're less characters and moreso just designs.the first one is a hacker who impregnates unlabeled usb grubs with colonies of computer parasites and leaves them in public places; the last one is a therapist who people come to when they're feeling listless and peaceful and he jams a metal rod up their nose and shakes it around until they get violent again; and the middle one was inspired by Siouxsie Sioux visually but i never really came up with anything for her.
