An spinoff/alt version of Beyond the Outer Gates Lies... by gabriel blessing. Originally written to show how Reya might join Harry's harem, though now has grown beyond that, and further from the original (maybe? probably?)
An unexpected encounter with a mysterious coin will link Izuku Midoriya to heroes from before the time of Quirks. The Power Rangers. But what happened to the Power Rangers, and will their remnant power be enough to make Izuku a Hero?
Midoriya Izuku always wanted to be a Hero. But now he bears that burden for more than just himself. With the power of The Gamer, he just might be the next #1 Hero. Izuku as The Gamer. Massive x-over story, expect changes to the 1-A roster...
A canon spinoff/interquel of Beyond the Outer Gates Lies… A high school library? Sexy times between Harry and his girlfriends that won't fit in the main 'Teen' rated story'. WARNING: Textual depictions of nudity and sexual acts. Not for children.
An expansion of the Heroic Spirit/who is archer discussion from Chapter 31 of In Flight by gabriel blessing. Meant to be mostly tongue in cheek.
An alternate ending to the Full-Bring arc, and potentially a version of the Thousand Years War arc reflective of those changes. And yeah, "Omake 449" is canon for this, though don't expect it to come up much.
A reimagining and retelling of Sailor Moon from the beginning. Very different from canon, the Senshi represent different elements and the goal of the Dark Kingdom is different (just for starters).
Kite and BlackRose (.HACK) and Kirito and Asuna (SAO) attempt to find the missing players of Elder Tale (Log Horizon) only to end up in said game themselves.
