League of Extraordinary Gentlemen: Teams Are Cool

"Teams Are Cool" by Dean Trippe

A NEW LEAGUE FOR A NEW ERA

A Copper on the Edge,
the Boy Who Lived,
a Misfit from the Future,
a Madman with a Box,
the Consulting Detective,
and a Ghost Roommate.

If you're familiar with Alan Moore's League of Extraordinary Gentlemen, you'll appreciate Dean Trippe's contemporary fan-art update. From what I can tell, the team consists of Harry Potter, The 11th Doctor, the modern-day Sherlock Holmes from Steven Moffat's BBC One series Sherlock, Annie the ghost from Being Human, Simon from Misfits series 2 forward, and... Luther? That's my best guess for the 'copper on the edge', anyway.

Here's the full-sized poster version of the piece.
