Once a lowly Pit droid working at a mechanic repair-shop, abused by "owner" because intentionally/accidentally destroyed ships. Got fed up. Stowed away, and joined a droid liberation movement. They upgraded the chassis, and stocked it full of explosives. Got first gig as a saboteur/demolitionist with them. It didn't pan out. Fled the repercussions. From everyone involved. Took a few odd mechanic jobs, committing occasional destruction for fun. Caught by the Rebellion after blowing up a shipment of something. Guess it was something important. Under threat of reprogramming and the reward of targets for demolition, paying off the shipment's debt as a saboteur/demolitionist.

Conflict: Mayhem
Demolitionist, whadya think?

Cause: Droid Rights
Self-freed (via escape), and a once-member of a Droid Liberation Movement

Debt: Blew up the Rebellion's shipment of... well not sure what. Paying off debt (under threat of reprogramming and reward of direction/practice as a demolitionist) via demolition/sabotage work for the Rebellion.

A gray, black, and ruddy brown DUM series Pit Droid designated as PT-C11, identifying as Pitch. Is slightly sturdier than the average Pit droid thanks to some fortifications and supplies via a Droid Liberation Movement. They equipped Pitch's chassis with Fabricator's Protective Gear upgrades, a multi-tool hand cybernetic, a fusion cutter installation, some improved processing and memory banks, improved servos, and the black paint job that resembles dripping pitch. Pitch is a bit of a pyro, but the addiction is largely inspired by boredom and leans towards destruction than a particular fire fetish.
