on fan characters

[Luciferr]

[color=black]Most of mine are OCs based in that world or OCs from my own stories - so I usually have them either transported here with the storyline generally being done before BoB (in the case of my sith lord and my grimm fam) or they're OCs of creatures etc fro there (such as my xenomorph character or even silentgrave to an extent).

but its perfectly fine to have em based on an existing character or straight up have em magically stuck here in an animal body (like with the Roy Mustang r the old RvB Crew in the ascendants) - just if they're not your characters or OCs based in that universe you obviously can't claim em as your own like grimm says.
