No particular story behind the nickname, but a small story to getting to the nickname.
I decided that I wanted to get a new nickname to doge anyone that is able to put my nickname and my email address (and as a result my name) together, so I ended up abandoning my old account (I was never banned, I still have that account, just don't use it anymore). Got a new nickname, "1234567", went to make one my first post in TK, got called Eks a few times. MickyD asked me who I was, and he said all is good. A few of the TK members know my old nickname (the one I abandoned). Eventually, after much nagging in TK I change my nickname to Genisys. Think the inspiration was Terminator. It is one of the many aliases I use online. I still use the old nickname but not for forums.
As for no profile pic, I don't like personalization of anything, I prefer to keep things stock and not change it too much. I'll likely get a profile pic some time.
