Hot off the press. This version of 13 is very skeptical and nihilistic, hanging off the edge of complete cynicism. They question everything with very little self awareness, leading them to believe everyone else is confusing and out to destroy them.
They are typically depicted as angry, getting shit-faced, or being deep in thought. Robert Crumb is one of their biggest inspirations.
