Usually it's just stuff I like, or stuff that's going on (ie that Alan Rickman one I had for around a month). My first avatar was a picture of a deku nut - I'll give you two guesses where that one came from.
My current one is a mix of a few things. He's from one of my favorite comic series of all time (Sonic Archie), looks awesome, and all that good stuff. But he also has a personality similar to how I picture myself in my head. Not only that, but I question good and evil a lot for being an agnostic, and using him instead of Sonic kind of symbolizes it. I know they were far from the first ones to use the conversation (The Dark Knight did it much better), but their version of the exchange left the biggest impact on me, probably because it was the first time I'd heard it:
Scourge: "As for you... I know why you hate me... it's that all it takes is one bad day, and you'd be just like me."
Sonic: "No, that's not it, Scourge. It's because all it would take is a little bit of selflessness... a little bit of decency... and you'd be just like me."
So, overall, this one has a lot of inner meaning for me, compared to the more shallow ones I'd taken up before.
... whoa, that started to get a little deep there. We need to lighten this up some.
