Summary
Mammon let out a loud groan, staring down at the papers that laid scattered out on his desk, pen in one hand as he rested his chin in the other. His third hand’s fingers tapped against the wooden desk. Mammon’s eyes narrowed as he stared down at the paper he had on top of the pile of the others, sneering as he read the contract.
It was some stupid mother fucker asking for a part of his precious money in exchange for a piece of the ring, that he ruled over, so he could build another cheap attraction to squeeze as much money as possible from some idiot demons that most likely were tourists. Mammon felt anger swirl in his chest as he snarled, letting out a sour growl as his grip tightened around the pen, only seconds away from snapping it in half.
How dare these rotten creatures ask so much from him, he was Mammon for Satan’s sake, he was the embodiment of greed itself.
Mammon’s fists clinched up into balls as he let out an unpleasant growl, slamming the pen down onto the desk before snatching the paper up, harshly wading it up into a ball before flinging it into a nearby bin. He bared his teeth like a feral animal as a puff of green smoke fumed from his clenched fangs.

Summary
Robo Fizz was commissioned by Mammon as a replacement for the One and Only Fizzarolli. A children's entertainer and performer, nothing more, nothing less. The toybot is a personal companion at his core, and, being assigned to Mammon as the one who purchased him, would do anything for the Prince of Greed. The Prince himself has no interest in entertaining any of the robot's companion roles however, leaving the robot feeling rather unfulfilled in his directives. This causes the bot to act out to get the attention he craves from the demon he's supposed to be catering to. Robo Fizz knows his master could use a true personal companion, but can he break through the barriers Mammon has built up around himself without ending up decommissioned?
