This story veers off from canon. It IS set during the Secret wars but follows an Alt continuity where Peter finds himself in an NY that neither respects nor recognizes him. Venom has been killed sometime prior to Peter's resurrection, thus his enemy turns out to be SCP 682, created not by the SCP foundation, but a different Company altogether.

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)

Containment Breach by joecola00 reviews
One-Shot. First written by me as a response to one of the Prompts for the 280th week of the weekly Writing Prompt Wednesday on the RWBY subreddit. Definitely a shorter/bare-bones story, but I found it entertaining enough to myself that I figured I'd also put it on FFN.
