Pure Good Heroes who suffer some sort of mental disorder that affects their behavior and personality. It doesn't necessarily mean that the hero is insane even though they do come across as such. These heroes are also Tragic, in a way that they are usually unable to understand what is right or wrong. Despite this, they have have a sense of clear moral agency.

Not all heroes are mentally unstable to begin with. Some of them are, but others are sane, and a few are stable, but then suffers terrible experiences that cause their sanity to snap.

Do not add the Dissociative category to Mentally Ill because this category is a subtype of mentally ill and it would be redundant as both of these categories are different in their own ways.

Pure Good heroes can be this if they do have an acceptable understanding of right and wrong and meet all criteria, despite their limited sanity and limited views on reality.
