Golan the Insatiable (2013) IMDb
Seen in 2018.
According to the season 1 opening title sequence, evil overlord Golan was ousted to our dimension by unnamed heroic-fantasy adventurers. This is retconned in season 2, a.k.a. the reboot, where Golan is actively summoned to our dimension by a hateful grade-school kid and that kid no longer has a father. Golan is not from the Golan Heights in either version.
Sitcom. Even eight years after Avatar: The Last Airbender (2005), American animators seem to feel the need to make shows like this deliberately ugly. Most adult characters just have a circle for hips. It’s admittedly prettier than The Ren & Stimpy Show (1991), and the subject matter is certainly grotesque, mixing dark fantasy with dark 1980s sitcoms like Married... with Children (1987), but as usual, the writers soon succumb to idiot-balling and life-affirming family moments, making the ironic sitcom merely a sitcom with dismemberment.
