this in what a book that was at least trying to present itself as an official Gurren Lagann artbook, though neither he nor I am sure whether it actually was or not-- he didn't take a pic of the cover, and doesn't really remember what it looked like, so we can't identify it for sure.
But this is too cool a concept for me not to offer up for your amusement. Kamina on a Segway. That's absolutely awesome-- in the hilarious sort of way, of course.
What other unusual vehicles can you picture Kamina riding in? Popemobile? Paper airplane? Cycle-copter?
