Game of Thrones may not have had that much Targaryen representation, but House of the Dragon completely changed that. In that spinoff, we got to know the full spectrum of Targaryen personalities. Some are full of righteous fury, like Rhaenyra, while others just seem straight-up evil, like Aemond.
In the latest Game of Thrones spinoff, A Knight of the Seven Kingdoms, most of the Targaryens seem chill, actually. Baelor, the heir to the throne, actually vouches for Ser Duncan the Tall so he can join the lists. Maekar is a bit aloof, but he’s worried about his missing sons. There’s one big exception, though. Aerion Targaryen, played by Finn Bennett, is on the extreme evil end of the spectrum, and we get a clear image of that in Episode 3. However, that’s only the start of what makes this character crazy.
