This robot – the mascot from JJ Abrams’ production company Bad Robot – may be the best cosplay costume we saw. This officially licensed Arkham Asylum Joker costume accessory kit includes a green wig, gloves, mortal kombat female costumes and functional squirting water flower. We caught him a few times, this time slurping out of a Slusho cup! Shout out to Ash Ketchum, power ranger adult costume too! One of the most original Deadpool outfits was this family of Nintendo-inspired characters.
