Finally Halloween came and you are as excited as a kid

Over the day you and the Task force were on some missions, did some briefings and cleaned the base a bit. As it was finally time to get ready, you started, with help from Soap and Gaz, to decorate the base and get the food ready

As you were finally done, you and the rest started to dress in your Halloween costumes. Soap was a werewolf, Gaz a mummy, Price a pirate and Ghost a...well...ghost As what did you dress?
