The Origins of Ganon: Ganon vs The Gate Guardian by Zelink fan 354
An imagining of Ganon in the place of SCP-682 with elements from both the LOZ universe and SCP universe. Rated M just to cover my bases just in case because of language and descriptive gore in battles. No sexual content, just language and graphic injury. Don't have a clue on what genres to assign for this so please let me know in reviews. (Says BOTW, but really all of the games)

SCP-MINUS by Anime0CC0Manga reviews
Before you read, I must let you know now that this is a AU Kumagawa and not the same character you're familiar with, so unless you don't wanna read a character with a darker back story and is, oddly enough, a reverse trap, do not read this. (Kumagawa will obviously act and be the same, but the only difference is that Kumagawa is a bit more, grounded character, if that makes sense)
