Time Slime is a demon from the Chest of Demons with the power to control the flow of time.
Time Slime is a tall, cadaverous man with pale green skin, bald head, elongated chin and blue goggles. He also wears a blue cassock with a broad collar and a clock insignia on his chest.
Time Slime is as ambitious as he is tyrannical. His objective of world conquest seems only for the sake of defiling the world and having everyone under his rule. He is abrasive to his subordinates (he browbeats Boogle and Weerd, even more so than the other demons). He is very rude and has a penchant for designing elaborate demises for his enemies, which is his undoing -- when Scooby, infused with an uncharacteristic bout of courage, attacked and eliminated his trap, causing it to backfire.
The 13 Ghosts of Scooby-Doo
Scooby got a view of the future that would happen if he quit and let Time Slime win. As Vincent Van Ghoul said, "Everything went wrong." This is an understatement, the world in the future is a post-apocalyptic junkyard, with very few people left (or at least wandering around). Now it seems that Time Slime's conquered the world, but he doesn't seem to be doing much with it, but defiling it. Flim-Flam (who's called Slime-X now) and Scrappy (who hails Time Slime as his hero because his Uncle Scooby abandoned him being a chicken when he quit the gang) have become disciples of Time Slime and wander the wasteland on motorcycles looking for victims to torment. Daphne has been enslaved and she's forced into endless pointless labor (cleaning a dungeon). Oddly, she says that she enjoys working for Time Slime, but it is also apparent her sanity is severely eroded. On the other hand, Shaggy has gone Bananas, believing fervently his old friend Scooby will come back and somehow turn this horrible world around, in fact, this seems to be the only coherent thought his mind can contain at this point.
How far this alternate reality is in the future is never made clear. Scrappy and Flim Flam still seem to be pre-teens, but Daphne and Shaggy both look 20 years older (this of course could be due to this nightmare existence causing them to age prematurely).
