I love my avatar and I refuse to change it. Rey is bae.
. . . Is that who that's supposed to be? Rey, from the new Star Wars movie? The fucking Feminist version of Luke Skywalker, who's only personality quality is that she's inexplicably good at everything? Ya know, that's actually a perfect avatar for you, Thunder, because the only way you'll ever accomplish anything of value in your life is through sheer fucking luck. Don't take that as antagonistic, though.
As for me, I like to change my avatar from time to time, usually depending on what I'm interested in at the moment. I had that Sans avatar for a while. When I came back after my hiatus I had a Homestuck character as my avatar. But I always seem to come back to the hunky Dunsparce fan art. But I think I'll change my avatar again, now, just for the fun of it.
