Disorders in the Mazinger franchise

Almost every main character in the Mazinger franchise has an equivalent of ADHD, hyper empathy, OCD, depression, sociopathic tendencies, the ptsd spectrum or narcissistic tendencies. 

For Toei Animation’s usual incarnation of Tetsuya Tsurugi, he definitely has a moderate but still agitating mix of depression and OCD as well as having a pretty mild (though still traumatic) case of emotional dysregulation disorder and fluctuating (albeit generally modest) narcissistic tendencies, which are mostly coming from being pressured to near death and from the considerable dysfunction that his late birth parents might have inflicted on him before they died. Even by Toei’s usually (relatively) fluffy standards, his self esteem can indeed be treatable but remains fairly notoriously damaged, albeit not to the nasty extent that has plagued Asuka Langley Soryu’s manga incarnation to smithereens. The other manga and anime incarnations, usually written by Go Nagai but not often animated by Toei, are probably just as edgy or troubled, if not more so, while their Toei Animation-based Shin Mazinger Zero counterpart is both a bioengineered clone and a terror who deserves more respect than what he gets. 

Of the many incarnations of Koji Kabuto, the original Shueisha manga incarnation probably tops them all in traumatic backstory terms; he both unknowingly and possibly had a much milder but still agitating case of something similar to complex ptsd, which was coupled in tandem with a home life nearly as awful as that of Asuka Langley Soryu in the classic Evangelion manga. Heck, even Shin Mazinger Zero’s own Toei Animation-based incarnation of Koji Kabuto is a fairly close second to this one, though the latter’s premise is far darker and more depressing than those of most incarnations. 

For both the Shin Mazinger and Shueisha manga incarnations of Juzo Kabuto, they mostly share a tie in terms of unintentional mental illness related moments that were outrageously funny for their time, but are now considered to be pretty much harsher in hindsight than they were when the original Shueisha manga was made, though there are some differences. Almost all the other incarnations are considerably saner than these two. However, Shin Mazinger Zero’s Shueisha manga-based incarnation of Juzo Kabuto’s Dimension 2 counterpart is the only one to be a deadly unhinged psychopath outright, which isn’t any better in comparison. 

Hey, even Toei’s own Sayaka Yumi variant is also mentally unstable, just not to the extremes of Asuka Langley Soryu in the old Evangelion manga as written above. Although considerably saner variants appear in numerous official Mazinger mangas and anime spinoffs, there are Mazinger Zero equivalents of the same name which have outpaced even the Toei version in terms of mental instability.
