Because the avatar feature has been shut off - nobody can use it.
If anyone had an avatar before the board was revamped a while ago then you can keep it, but you only have the choice to delete the avatar - can't add a new one.
Wolverine gets my vote if only because of the new gif. It IS a shame that the avatar function has been shut off, but obviously, it can be got around.
That keyboard pounding gif cracks me up every time I see it.
