My episodes usually follow a two-part naming convention inspired by the style of titles that a lot of anime use.
I choose something that conveys the tone of the episode and an event in it, but try to avoid outright spoiling the end. There may be punchlines (or wham moments in serious episodes) I want readers to see for themselves!
The first episode is “A Blast to the Past! Here’s to a New Beginning!” since it portrays travel to the past, and marks the beginning of the reboot!
I also throw in puns, pop-culture and music references when I spot an opportunity for them! (I.e: “The Space-Time Continuum Crashes? It’s the End of the Timeline As We Know it!” and “Summoning a Fearsome Witness? Hells Bells!”) Some music titles came from looking through my music library for inspiration!
