Charlie X

Charlie is an irritating youth, easily angered, who then likes to glower, his teenage tantrums and infantile temper, often lead to a display of his power. These powers are super-hero like, so he uses them to intimidate and threaten, but with or without these skills, his power to kill, he's still the most irritating cretin.

A notable episode, if for no other reason than Kirk's inability to explain why smacking the derriere of a lady you've just met is completely unacceptable, no matter when, where or by whom.
