anyway, what are you asking?
My own oc He is on the fanon wikia for RWBY if you want to look at him his name is Northkolrwolfe Vincent Valentine He is a wolf faunus who was born outside the walls of vale and was raised in a roaming village that was deimated by beowulfs but was raised by a Huntsmen and Huntress couple who found him just after the village was killed and raised him as their own child.
We already have a established line of main cast, as this project has been ongoing for quite some time. That being said, it may be possible to include characters in a minor role. I have checked your character page, and one problem that I have noticed is that your OC has just started attending Beacon, which is not exactly compatible with what we have in the main plotline at the moment, as it is set in a location quite far from both Beacon and Vale for the most part. To have a chance at having your character appear in the series, you would need to resolve this problem first.
