Nintendo Switch: console playing console cosplay02 October 2017
You could see a truly original cosplay at the recent video games festival in Tokyo. Not only did someone come up with an idea of making a Mario cosplay with a Nintendo Switch console as a head, but they also made it look amazing.
The highlight of the image was the cosplayer himself playing the game on Nintendo Switch, while wearing this costume. It looks like a console with the body of Mario plays itself (recursion!). And judging by the video, does it really well. Mind-blowing self knowledge level.
