Helmazaria is one of those characters who is just a little too cool portray correctly with ease. I didn't quite do her justice. 

 She is a legendary space knight renowned for her valor and brutality easily outrunning Tetsuro on their first encounter, which is no small feat. She's also a Metanoid, which are biological people whose skin, muscles, organs, and bones are all made of metal, making them one of the most resilient races in the universe, nearly unkillable. 

 I actually like how she was used in the film 'Eternal Fantasy' better than in the manga. She fills the same role, but she comes across as much more of a threat, and her and Tetsuro's second showdown is far more climactic and hair easing!! 

She's got rad armor to. The only thing I didn't have time for was the hexagonal pattern on her arms and legs that is present in the manga. I stuck with her look from the film, mostly.
