Myron

Myron The Mildly Irritating is the brother of Trigon and the uncle of Raven. He made his debut in the Scooby-Doo Crossover comic, Teen Titans -- Ghost! Part 1.

Bio
When Myron The Mildly Irritating first appears, the Titans assume he is there to take over the world, just like his brother would. Myron explains that he is not there to conquer the world, but rather he is there to visit his favorite niece. When they learn he has no evil intentions, they welcome him into their home. As his title would imply, he is very irritating. He quickly gets on the Titans' nerves. The Titans become fed up with his behavior, so Mystery Incorporated (who had just helped the Titans solve a mystery) offered to teach him manners. Everyone's attempts to teach Myron manners fail, so the Titans decide to kick him out.

In their attempts to get rid of him, Velma discovers that Myron is a crooked real estate developer from the Netherworld. His real reason for being there was to annoy people into moving into the Netherworld, allowing him to make money. After uncovering his nefarious plot, the Titans threaten to take him down. Myron leaves willingly, claiming that they are all far more annoying than he ever was. With that, he travels to the fifth dimmension, hoping to have better luck there.

Trivia
