So how much of TMNT does Viacom/Nickelodeon/Paramount actually have control over?

I wonder if that list includes Ninjara? She appeared in the Archies Comics, But wasn't a character created by Eastman and Laird, But someone else. And she appeared in 3 issues of a comic called Furrlough, by Radio Comix after the Archie Comics were canceled.
