ADHD amongst other things so I have a lot of nicks.
neuroman from when i first learned i was autistic. superman my childhood hero. sure can't be superman, but can be neuroman. i had the whole superman thing transliterated to neuroman's characteristics. i think it's still somewhere on WP in my profile.
tinkerjack = jack which i don't use anymore to avoid confusion. i am a tinker and a jack of all trades. jack is also a part of me that's seldom activated. when i wear that hat i have much higher verbal and analytical skills. that part of me is also a really good cook while this part of me manages to burn water on a regular basis.
wolfish = IRL nick is wolf, but also voracious when it comes to reading books. i also like fish.
hyperman = that was before i got the hyper part of the adhd under control
