The current Jaw Titan inheritor is Falco Grice. He is a Warrior cadet and a Marley Titan candidate who transformed into a Pure Titan. But he quickly regained his human form when he consumed Porco and inherited the powers of the Jaw Titan.  His unique character design and features appear to be a byproduct of the Beast Titan’s spinal fluid. As the current Jaw Titan, his form sports wings, a tail, and a fully feathered body.
