L

L is a viridian Letter L. He has two uneven shaped eyes in the middle of his body. A small hole is seen on his lower protruding end. His superhero form has extra muscles, reflective eyes, and dark green hair. His buttocks is notably visible from behind. L is a very snarky, sadistic and rude letter who likes to bully F and N. He mostly cares about only O and himself, as shown when teamed up with the latter or looking at his reflection in the calculator ship button. L, along with o, first appeared wanting to target f, r, i, e, n, d, and s. l scared away r, i, e, d, and s and then launched o in n's face, much like a rubber band, and laughed with O about it. f got revenge for n by pranking him and spelling the word "fart" to embarrass him in front of b, c, d, e and h laughing at him about it. After this, l beat him up with the help of o and f tried to get them back again by spelling the word "frick" but instead turned all of the other Letters against him. L, along with O and M, intimidated N into siding with them instead of standing up for his beaten-up friend. This is what ultimately caused F to turn evil. Somewhere, before F's attack, L turned into an adult. In L, L says his name and then does a Sailor Moon-esque transformation. He then blocks I's cannonball shot by F, saving A, B, C, and G.In O, after N runs away, L is shown as disappointed in N's work. In R, after F steals N's gem, L pushes him and flies away with O, tracking down F. In S, after F slurped S, L uses his. a gem to freeze F. Unfortunately for him and O, F uses his; gem on O and L, connecting them and shrugging off the gem's ability. He then steals L and O's . and : gems. In Y, L and O witness the ray shot by N.When Z turns back time, N decides to take F's side, leading L and O to beat both F and N up and declare both of them outcasts, but both of them are ok with this and go to the cave to keep each other company. L still receives his gem. In the 3rd episode of Number Lore, L debuts by entering O's hole and prompts the two to transform into their superhero forms and go after the calculator. They successfully make it and find X, but are brutally beaten up by 2, and get run over accidentally by BIKE. F thinks it's absolutely hilarious to see their fate. After a few failed attempts from other Letters, L successfully traps 3 with his period gem, empties the numbers and their machine out of the ship, and, seeing F sad in the cave and remembering the time he set everyone up and still being proud of that, launches the ship at him and into the cave's opening, much to the horror of N.

In 4, he is seen laughing at the destroyed cave, then J, E, R and K is shown spelling JERK, indicating that some, if not all of the other Letters are now aware of his true egocentric and condescending nature. He then flies off to F's cave. He offers an insincere apology to F, who hides from L. At one point, he admires his reflection in one of the calculator ship's buttons, but unfortunately F shoves him in, therefore trapping him in the process. He tries to break out with his period gem, but L made his situation a lot worse by freezing himself since the period gem's laser bounced off the button and landed on L himself. Later, he watches F follow his gem while N unsuccessfully tries to get F's attention. F's gem repowers the ship while coloring it black with a white halo. He shouted for help as the ship levitated since he was frozen in his bubble, and N blasts his semicolon gem into the cracked bubble to link their gems so they temporarily reform the ampersand gem. Once N did it, he pulls F through the Calculator, and L is seen bored‌, but F hits his bubble that causes him to move again. He helplessly watches F get to the launch button as N tries to stop him since he was still frozen in his bubble. Once the Numbers reached F's cave, 1 notices F hijacking the Numbers' ship, and 4 boosts her and the Numbers' way up by making roots underground. 4 tries to restrain the ship, but this backfires because O's gem breaks while N's gem flies into the Calculator as L watches in horror. L is last seen calling for help as he, F, and g leave Planet Z and go to Planet 0.

L made a cameo in 5 as P and G watch him and g Jr. leave Z in the Calculator
