Well, my username is just what I came up with when trying to think of a cool sounding name. I don't remember what I originally used it for but I do know that I've been using it for several years at this point. It is one of my two most active names and I use it in a wide variety of places but I do know that I have seen people using my name, so if you see my name being used somewhere, it's possible that It's not me.
As for my profile picture, I've been using a picture of Zack Fair from Crisis Core as my main profile picture ever since I first played the game back in high School. He was one of the first characters who I really felt attached to. Prior to this, I was using Castlevania characters. Ever since Crisis Core got a remake, I've been thinking of going back to using Castlevania characters again but it just doesn't feel right to me anymore.
I do also want to mention that I do also use a picture of Clippy as my profile picture on some platforms. I've been doing this ever since I saw that one Louis Rossmann video and I use it on platforms that I don't support.
