Sketchbook-430
Sketchbook-430 was a Mark V Clockwork Cherub and a member of the Crew of the Copper-Colored Cupids' Department of Entertainment.
In 2019, he worked on The Rainbow Adventures, notably providing a story outline for an episode involving malevolent robots known as the SavageMen. Due to a miscommunication within the Department, a team led by newly-recruited Paintbrush-122 wound up developing their own rendition of this episode as The Death? Planned It! while Sketchbook's own team further developed the concept and completed their own version as The Moonbeams.
The mistake was noticed before release, and a line was hastily dubbed into The Moonbeams about the Rainbow Kids having encountered the antagonists, the SavageMen, before. When the two episodes premiered back-to-back at the Cupid Theatre, however, Sketchbook and Paintbrush were considerably more startled and dismayed to realise that their respective designs for the SavageMen were almost identical despite their lack of communication, above and beyond what the script specified. After breaking out into a fistfight, they were brought before Judicator-337 by Larrikin-1029 (who had caught them in a burlap sack), but no real clarity ensued as to who if anyone had ripped of whom; instead, a Rift opened in Judicator's office and allowed a group of visiting real-world SavageMen through.
The SavageMen asserted that they were the only rightful owners of their own copyright, and insisted on being credited as such in all subsequent episodes of The Rainbow Adventures featuring their fictionalised counterparts. Fearing that they could similarly encounter any new monsters they “created”, both Paintbrush and Sketchbook declared that they'd give up monster-design altogether from now on, and devote themselves to still lives of potted petunias.
