This is a beast of a cosplay video. We’re familiar with the cosplay montages that come out of conventions these days; a few minutes of music and some of the best cosplay. They’re wonderful ads and awareness pieces for the booming convention scene.

This particular video from Beat Down Boogie is nearly 30 minutes long. It’s pushing into documentary territory. Or musical documentary.

Too long to view? There’s some picture highlights below and more on Facebook.
