Here's a really ambitious bit of cosplay. The photograph was taken by @luckycreature on Twitter, but I don't know who actually did the cosplay.
For those who aren't familiar Prince Robot IV is a character in the excellent sci-fantasy comic book series Saga written by Brian K. Vaughn, drawn by Fiona Staples and published by Image Comics. If you haven't read it you should. Now. I'll wait.
What's a really nice touch here is that the cosplayer managed to have Prince Robot's head functioning.
