Shonen Rivals whose morality is solely "Truly Neutral" since they are morally-ambiguous individuals. They can be Anti-Heroes, Anti-Villains, and even Antagonists since "neutral" characters who do not attend to do good nor evil but can be sporadically "heroes".

Their morality is enough decayed to be questioned; their exact nature is debatable, and therefore impossible to truly determine, and it is up for the readers or viewers to make their judgment: while some can see them as heroes, even if they do not approve their methods, some will see them as criminal or even villains.

On & Off characters who commit at the same time heroic and villainous deeds, such as some incarnations, or false heroes known as "Heroes by Proxy", also belong to this category.
