Bolaji Badejo's Beret

Origin
Bolaji Badejo (1952-1992) was a Nigerian graphic designer and actor, best known for playing the Alien in Alien. He was discovered in a bar by a member of the film crew of Alien, who felt that he would be ideal to play the title creature as Ridley Scott wanted to create a monster that looked as if no human could be behind the mask. It was to be long and angular, with an impossible frame that few people would be able to fill. Even though he had no training or experience as an actor, Badejo's thin, 6ft 10in body made him ideal for the part. He went to tai chi and mime classes to prepare for the role. This beret was given to him by the teacher of the mime class.

Effect
When worn, the victim will slowly begin to mutate into an alien-like creature, similar to the alien from Alien. The victim will be killed during the transformation, due to their blood being turned into acid.
