Shleemypants is a red, vascular monster who appears to be made of internal flesh with several small little hairs on it. His only facial feature is a giant mouth full of crooked and disordered yellowish teeth. He has long arms with three fingers and a thumb on each hand (described as vestigial, yet still functional) and no legs, his body simply floating off the ground. He wears a long tan robe that is very ripped and torn at the trim and ends of the sleeves. He also wears a brown satchel, used for storing his equipment.
Shleemypants is a very sassy, trash-talking creature who does not take shit from anyone and gets very rude and even violent when angered. He talks and acts like a stereotypical "angry black man". He enjoys using the word "ass" as substitute for other curses.
His omniscience is both a strength and a weakness, as Rick and his family simply created many overlapping timelines to overwhelm and defeat him.
- He is a parody of the Time Eaters from The Langoliers.
