Robin

This would be me, the author and main character. 26 years of old age, artist wannabe, part-time lazy bum, full-time slacker. Has quite the awkward household, amongst which a sentient carpet and a small whale. Nobody knows or ever dares ask where he keeps it. I happen to know, but I'm not to tell, under penalty of suicide. I'm a harsh mistress.

Jack

Lil' ol' Jack. Robin's known the bugger for far too long, meaning around 13 years, and he's 26 too. I can't be bothered to talk about him any more at the point. He likes black. A lot.

Ben

Ben is (far too often) Robin's partner in crime. As can be seen in the 24 hour comic, ehr, comic. 27 or 28, I never remember, but he's old. He has glasses. And arguably more eyebrow hair.
