F x N

(Your N) F is a black letter F. His eyes are located at the top back of his design and his jaw is the two extended lines, which contain spiky teeth from when J hit him in the mouth as a kid. He is also known to be made of some sort of inky substance. As a child, F was a nice, cute, happy content letter who got along with many of the other letters. His appearance as a child represented a lowercase F, with straight teeth and a smile, when he frowns, he looks like a normal lowercase F. As an adult, F became ruthless and wanted revenge for what the other letters did to him in the past. His appearance became a capital letter, and his teeth were broken towards shards. His smile disappeared and was sneaky with deception similar to a snake. F appears to be less vengeful and hostile to N because N stood up for him, but still resents L and O for ruining their childhood. He still has a similar appearance but has broken teeth and minor bruises, him and N now live in his cave (I guess idk)
