Loki

Loki is a Halloween costume for Pancake Cookie featured in Halloween Party events. It was first, and only, usable during Halloween Party 2016. However, after the event period, the costume would no longer be accessible.

Being based on the Marvel Cinematic Universe version of Loki, this costume puts Pancake Cookie in an outfit akin to the famous supervillain- specifically the classic iteration of him.

Unfortunately, like many other Halloween Party costumes, this costume is completely inaccessible in any other Cookie Run game and it is currently not known if it will ever make an appearance again, very blatantly due to copyright reasons.

Trivia

 * Both Roll Cake Cookie and Pancake Cookie have matching costumes, Loki and Loki respectively. This is because both the Cookie Run duo and the Marvel Cinematic Universe duo are brothers.
