Mudd (Roger C. Carmel) is a con man who Kirk discovers is trading in dodgy women on two occasions. In
, he uses drugs to make three mingers appear beautiful; in rematch
, he's created a harem of lady androids.
In the reboot's altered timeline, this Mudd is more psycho than rogue, whose android-building capabilities are to be used to take over the Earth and position himself as leader.
Kirk gets it on with one of Mudd's women, only for her to transform into a robot assassin.
