Grimdark!Rose Lalonde from the webcomic/Internet phenomena/bizarro ride called Homestuck. So, a thirteen year old girl in a pseudo-consensual deal with gigantic space tentacle aliens for powerups (sort of) triggered by the death of her mother and a pedofork puppet with a cue ball for a head and holy shit that sounds really bad out of context.
(GDT actually stands for grimdark throes.)
