Dogtooth

I don't know how to keep this short and sweet, because Dogtooth is an INTERESTING character, but I'm gonna try like hell. Basically, a Warrior Cats fan's dying wish was to live within the books alongside his favorite characters, and BOY did he get the monkey's paw treatment. He ended up as a background character (specifically a kit-warrior who survived Brokenstar's regime), and as any fan will know, the Erins have a pretty poor track record with background characters. He lasted for two series before snapping due to the constant pelt color changes, and eye color changes, and personality changes, and deaths... (I think he had Heavystep beat in that department, as a matter of fact!) To make matters worse, his two siblings (Snapdragonpaw and Shrikepaw) just up and vanished between books. Fortunately, Dogtooth happened to be the son of Quince, Scourge's mom, so he could exploit a loophole in the prophecy of The Three to bring them back... by killing Jaypaw, Lionpaw and Hollypaw. One thing led to another, and by the end, their deaths were just a drop in the bucket. He even ended up having to kill characters who hadn't previously existed; the books started generating even more kin of Firestar's kin to try and stop him, and these new cats seemed to have the same fourth-wall awareness as Dogtooth. (Other characters never really became "real," despite their actions and decisions changing because of Dogtooth; he likened their deaths to killing NPCs in a video game.) Even though their deaths brought his siblings back, they wracked him with guilt, eventually leading to his stay in Scrapville.

The only known "Dogtooth copies" belonged to an aspiring writer named Warren Innocenti, the cousin of the three children who would go on to become the murderous tom and his two siblings. Through some Olympics-level mental gymnastics, Dogtooth found a way to blame Warren for all the deaths he himself had caused, demanding that he do something to atone for the deaths of Redflower, Firelamb, Gorsemuzzle and the rest. Warren had recently obtained the rights to work on a Warrior Cats film, so Dogtooth proceeded to become That One Executive and demand loads of changes that (along with Warren's style, which wasn't suited for the books at all) ruined the whole production. The finished result (In a Dark Forest) bore almost no resemblance to the books they were based on- seriously, how do you make a Warriors adaptation without medics, StarClan or... well, any Clan not named Thunder, for that matter?! The whole affair ended Warren's film career before it even started, and Dogtooth (now in puppet form) wound up in Scrapville with all the other cats, left to wander the forests and think about just how badly he'd messed up.

Years later, Warren was back on his feet, and decided to try playing ClanGen to try and overcome his newfound distaste for something he'd once loved so much. Dogtooth decided that this would be the PERFECT time to make a reappearance, possessing the game along with his friends. He didn't have any malicious intent this time, only wanting to make peace with Warren, but when nightmarish glitches started popping up, pretty much everyone assumed he had something to do with it. And he did, technically- when he possessed the game, he had to override Warren's original ClanGen save. Somehow, what were originally lines of code became sentient in the process, and they were NOT happy about being abandoned. How'd this end? Well, given the fact that Dogtooth and the former ClanGen cats now coexist in Scrapville, probably well? But who knows lol
