- “I made a Pigeon-rat.”
Hugo S. Simpson II is a non-canon character and Bart's conjoined twin in "Treehouse of Horror VII". Shortly after their birth, they were separated by Dr. Hibbert. Since then, he has yet to make another appearance.
Bart, Lisa, and Maggie discovered Hugo after they heard strange sounds coming from the attic and after Homer spilled the beans about there being four Simpson children, As the "evil twin", Hugo had been confined to living in the attic of the Simpson home and once a week was given a bucket of fish heads to eat because he was the evil one. Hugo also did experimental surgery to prepare for his eventual reattachment to Bart, and created a "Pigeon-Rat" in the process. The family later learned, however, that Bart was actually the evil twin, as Hugo's scar from when he and Bart separated was on the wrong side. Bart then took Hugo's place in the attic and was fed fish heads, while Hugo moved downstairs to live with the family. Bart was let back down with the family after the dinner scene with Hugo sitting at the table.
- He was believed to be the evil twin but found out he was the good twin.
- In "Brother's Little Helper", when Bart was driven into paranoia due to Focusyn and went berserk, his facial appearance strongly resembled Hugo Simpson.
- He is likely named after his, Bart, Lisa and Maggie's great-great-great uncle Hugo Simpson I, whom he and Bart heavily resemble.
- The Chalkboard gag for "The Homer They Fall" is "I am not my long-lost twin," possibly referencing Hugo.
- In "The Girl Who Slept Too Little" when Bart is being dug into the ground, he resembles Hugo.
- In The Cad and the Hat, Bart's guilty conscience's personified form resembles Hugo.
In this 2003 video game, Hugo is one of the character costumes for Bart.
During the 2014 Halloween Event of the app-based game, Hugo was one of the craft prizes and had his own questline.
