When Robin selects the last font on the list for his presentation, it sets off the typocolypse.
Plot
Cyborg and Beast Boy are engrossed in playing with a video game with the two girls watching them, but the fun is ruined when Robin busts the TV with his bo staff and announces that it is the annual team assessment meeting, much to their chagrin. Robin then goes on with the first agenda, which is the team leader report, but then Cyborg notices that he has used Comic Sans for his presentation, and claims that Comic Sans is one of the worst fonts in history. Unfortunately, it turns out that Robin has used Comic Sans in all of his presentation slides, horrifying Cyborg, and Raven immediately figures out that he is a font snob. Cyborg instantly denies Raven's statement about him and refers himself as a font connoisseur instead, and gives out a presentation on how typography is an art form that will affect one's reading experience. Robin then submits to the others' requests and each time he changes Comic Sans to each font that Starfire, Beast Boy and Raven respectively request for--Papyrus, Impact and Century Gothic. However, none of them meets Cyborg's high standards.
Robin decides to break off the argument between the four other Titans, and decides to randomly pick Zimdings before Cyborg can stop him, consequently causing the typocalpse. Afterwards, Cyborg explains that Zimdings is a dangerous and loathsome font created by a man called Winston Q Dingbert, who they have to hunt down. He adds that Zimdings was booed and rejected when Dingbert announced it and Dingbert ended up being exiled to the Island of Garbage Fonts, and they have to find him in order to get him answer for his crime against humanity. The Titans immediately decide to set off to the island to search for him.
After arriving at the island via Raven's portal, Cyborg scans the island and assumes that Dingbert must be hiding somewhere, and prevents Beast Boy from moving forward because he believes that the contains horror that will haunt everyone for the rest of their days. However, it appears that he is exaggerating too much, and on the way the other Titans ignore his ramblings about anything garbage font related. They get into a battle stance when they hear some noises from the bushes, but it turns out the one hiding behind it is only an innocuous Dingbat. Cyborg threatens the Dingbat who is speaking in Zimdings, but the other Titans quickly figure out that the Dingbat is only trying to help them and scolds him for overreacting like any font snob would do.
The Dingbat then shows the Titans around their village, and brings them to Dingbert, who Cyborg recognizes. Despite seeing Cyborg's hostility, Dingbert acts friendly and recounts his story regarding his exile, claiming that the Dingbats are a tribe without their own language and that he has taught them Zimdings as a favor of them taking him in. Robin, Beast Boy and the girls are moved by his story, though Cyborg still shows some suspicions. His suspicions are confirmed when Dingbert sends them down a chamber where all the fonts are imprisoned, though he considers that Comic Sans deserves to be imprisoned. Dingbert reveals that as they clicked on Zimdings, the trap he set years ago has sprung and trapped all of the fonts as a result, and bolsters himself with the power of Zimdings, which easily overpowers the Titans. Robin suggests freeing the fonts from their imprisonment and harnessing their power, and one by one they transform with the power of Papyrus, Century Gothic, Impact and Arial Black, forming the League of Garbage Fonts. Nonetheless, their combined power is still inadequate against Dingbert's powerful Zimdings.
Initially, Cyborg refuses to merge with Comic Sans due to his prejudice for it, but after being pleaded by his friends who hope that he will give up his font snobbery to save the world from the diabolical Dingbert, he gives in and transforms into Super Comic Sans, giving him and his friends the ultimate power to defeat Dingbert. Later that day, after the Titans tie up Dingbert, the Dingbats thank the Titans and reveal that they have their own native culture, and that Dingbert actually forced them to learn Zimdings. After Cyborg apologizes for being a font snob, he reveals that he has learned the lesson that fonts have no good or bad and instead depends on how one uses them, before he and his friends resume laughing at Dingbert being brutally punished by the Dingbats. The "The End" segment ends with the font being changed a few times with Papyrus, Century Gothic, Impact and Arial Black before settling down with the usual font the series uses.
