This is 6, the narcissistic assassin of The Billiard Boys
One of 17 expys initially based on The Felt(homestuck) that were plopped into our dnd campaign (among other imported nonsense in our game)
6 is one of the more difficult members of the gang, for many reasons (mostly his massive ego) He’s not keen on following directions, nor working with others, so he prefers to be left to his own devices.
His own devices being his ability to summon a voodoo doll he uses to jump to different worlds. Though not in the sense that you’d imagine, nothing like the fire planes or the shadowfell or any other place that is still relevantly inside THIS universe.
6 has the ability to go to dimensions completely separate from this one, with their own reality and worlds. These usually have unusual minor differences, like the world where everyone’s gender is swapped, or the world where everything is green, or (his personal favourite) the horse dimension.
He uses this ability to hide from his enemies in the main dimension, in a different one. He sneaks through, jumps back to the main dimension, and gets the drop on his target with a swift execution.
The one fault in 6’s ability, is the fact he has to experience every time a doomed timeline occurs in his universe. This includes when several branch out from a single event, becoming temporarily shattered between them.
Once he is in a doomed timeline, a black pin will materialize in his doll, which he uses to travel back to the main timeline (if there were multiple timelines doomed, gaining all the memories from all his other doomed selves who also traveled back)
So despite being hard to tolerate at times, it should be noted that the gang and their allies should be at least a little appreciative to have the green bastard around. Because if he goes missing all together, that’s a sure fire sign that you’ve slipped into a doomed timeline.
