Hm, I have an orc OC based off of my orc in Skyrim. Her names Igrim One-Eye - I also have a few other characters that are of the supernatrual/anthro/half animal persuasion; Dunno if you're a fan of guro but there's a manga by the name of Franken Fran - she has a companion of sorts. He's a cat with a human males head, there's other mix ups as well who she interacts with on a day to day basis while her "father" is away on business. There's also a managa by the name of Judge it's a sequel of sorts to another manga of the same genre (the name slips me) it's about a group of folks being brought together (in a clean Saw like scene) and picked off one by one by one another. Each "round" they have to choose who to kill either baseless or based on crimes they've each committed depending on if they figure it out or not.

I also think it'd be cool if create your own story within Inuyasha completely apart from his and Kagome's. As I've always wanted to do this but never really seen anyone do it as a lot of fan girls just want his "D" and nothing story wise.
