H

H is a mint colored letter H. And H is a Ghost. Their eyes are located in the middle and in-between its mouth. Due to smelling "fart" as a kid, h remains deceased in their form, with black eyes and long horizontal white pupils. Notably, H has a few lost teeth. When h was a child, they were alive and possessed a normal, corporeal body. Unfortunately, they smelled the fart f created to prank and embarrass l, which killed them and turned them into a ghost. They had since remained as a ghost. They then saw how f spelled frick and like most of the letters, h glared at f and turned against him. Somewhere before F's attack, H turned into an adult, (but were still a ghost). In their titular episode, H, H appears, fading in out of thin air, saying their name. After that, F sprints to H and uses H to hide from A, B, C and G to get away from them by posing in behind H. After A, B, C, and G were gone, F inhaled H and farted them out, causing H to explode into many pieces.

In Number Lore 3, H appears for a split second in the cutscene followed with R. In Number Lore 5, E tries to get H onto the BIKE but keeps going through them. Eventually, E gives up and gets away from the giant 5 clone wave.

Despite being deceased, H is still capable of transforming
