Gender-bent characters of Star Trek
Mr Spock the half human, half Vulcan first officer and lead science officer aboard the USS Enterprise,
Captain James T. Kirk the rebellious leader of the USS Enterprise,
Dr "Bones" McCoy the grumpy chief medical officer aboard the USS Enterprise (and no, he is not in red because he is a 'Red Shirt', but because I wanted to mix things up),
and Khan Noonien Singh the ruthless augmented human and one of the most challenging adversaries Cpt. Kirk and the crew of the USS Enterprise have and will ever face.
(Khan's design was based more off of Benedict Cumberbatch's portrayal of the character, even though I do love Ricardo Montalbán's portrayal as well
