For a webseries about the alphabet, of all subjects, Alphabet Lore can sometimes be incredibly dark. After all, some things kids have to learn will not be a cakewalk…
- F's evil timeline. First, he locks up D, E, I, R, and S, and then he also kills C and X, and not just that, but he sets up G to kill P by accident.
- Speaking of which, the debacles of D, E, I, R, and S are nothing to laugh at. They are kidnapped in chains inside F’s cave. Even better, according to episode F, D and E are speaking, implying they are perfectly aware of their situation and can’t do anything to stop it.
- The way he kills letters are not much better, either. For instance, J is blown up by a laser from F using I while H is consumed by F and farted out. (Though it’s also a case of Crosses the Line Twice.)
- W is a pair of creepy Conjoined Twins with red eyes and their debut is in a black void, later revealed to be N's nightmare. They also do not appear that much, only adding to their creepiness.
- N's nightmare. Not only is he being shamed and being called a coward, but he is facing C and P, two victims he witnessed the deaths of, and sees the shadows of F lurking in on them. G blocks him from going forward to protect them, and when N hits him to make him stop, it's revealed that G is actually F. N wakes up after F in his dreams suddenly bites at him.
- R's design can come off as creepy, as he looks as if he was traumatized from witnessing horrible events, even as a kid. Even his lowercase design can come off as this.
- 2 absolutely demolishes his victims with seemingly infinite sets of teeth. B is one thing, but he goes absolutely full force at M.
- Apocalyptic World composed by Allen Gray plays in numerous scenes, usually when the worst is about to, or has already happened, such as a scene where F's silhouette lurks in on R, who happens to be doing nothing at the time.
- Each of the numbers after 1 seems to be looking more unusual and otherworldly than the last. 2 has an infinite set of large teeth keeping his mouth permanently open, 3 has a long blue tongue and yellow eyes with diamond-shaped pupils, and 4 (going by the silhouette) appears to have a serpentine body with fangs and horns.
