So I've managed to dig up a few OCs of the MLP staff (this includes the comics and chapter books) in the past but I feel it would be nice to have a compilation of all of them. I've searched Google and so far at best I can find one named OC at a time, at worst I hit a dead end, but pretty consistently I end up somewhere in between like an OC that might or might not belong to a member of the staff or a commission without a name. I'll go ahead and say those I already know:
Bittersweet is the OC of writer Katie Cook
Leadwing is the OC of artist Andy Price
Snowdrop is an OC representation of storyboard artist Raven Molisee
Sappho is an OC representation of artist Jenn Blake
Wild Fire is an OC of storyboard artist Sabrina Alberghetti
Holly Dash is an OC of animator Holly Giesbrecht

Hope you can help me in my search.
