Pugnavore

Pugnavores are a drama-hungry species from an unknown planet in the Milky Way Galaxy.

Anatomy
Pugnavores resemble Humans, except they have green skin and antennae on the top of their head.

Diet
Pugnavores feed on the emotions, drama, conflict, and aggression. As such, Charles Zenith hosted a reality show called The Most Delicious Game, which was primarily aimed at creating enough drama to nourish himself.

Powers and abilities
Pugnavores are capable of teleportation, as demonstrated when Charles Zenith teleported his show and contestants to various locales around the universe.

Pugnavores can read minds, as Zenith was able to bring every female Ben could remember to the start of the show.

Pugnavores have telekinesis, as Zenith manipulated his props on the show. Similarly, they can make themselves fly or produce shockwaves. Pugnavores have a degree of energy manipulation, being able to force someone in possession of Omnitrix technology to change back to their conventional form.

Weaknesses
Pugnavores cannot stand being bored. Because of this, they are vulnerable to being trapped in a nightmare revolving on boredom by a Nemuina.

Culture and society
Since Pugnavores survive off of conflict and aggression, they can't stand boredom. They have been shown to be very unsympathetic and care about little more than making and feeding on drama.
