IMO "speechless" should be restricted to characters which should and or could speak in a fashion, understandable to the audience, with others of their kind and story POV. Many "normal" animals still vocalize, so not speechless. Same for Robots. Some are designed to speak, some not.

I'm in favor of Mentally Ill having a few select distinctive subcategories. "Multiple Personalities"(MPD is an older outdated term replaced by DID, Dissociative Identity Disorder) is definitely one of them, and one of the few reasons why a character (not team or groups or species) might be tagged with multiple and conflicting alignments(which should be simplified too).

Other Mentally Ill subcats would be "Psychopath", "Amnesia", and possibly "Paranoia".
