Bartholomew JoJo "Bart" Simpson (born Sunday, April 1, 1979) is the deuteragonist of The Simpsons.

Bart is the mischievous, rebellious, misunderstood, disruptive and "potentially dangerous" oldest child. He is the only son of Homer and Marge Simpson, and the older brother of Lisa and Maggie. He also has been nicknamed "Cosmo", after discovering a comet in "Bart's Comet". Bart has also been on the cover on numerous comics, such as "Critical Hit", "Simpsons Treasure Trove #11", and "Winter Wingding". Bart also has a 100-issue comic series entitled the Simpson Comics Presents Bart Simpson. Bart is loosely based on Matt Groening and his older brother, Mark Groening.

Even at a young age, Bart has accomplished many feats. He has won an award for his Angry Dad web series[1], he has discovered a new comet which was named after him[2], and he also has performed in a successful band with Milhouse Van Houten, Nelson Muntz, George Collins, and Ralph Wiggum.

He started Young Life Records and got married to Amanda Simpson, known as rapper Rapsta Chik. Bart has two have twins Ryan and Delia together and nearly two years later had Abraham III. Bart and Rapsta briefly separated but renewed their vows, although Bart continued to see his girlfriend Kassandra Simpson on the side. Amanda and Bart eventually went their separate ways once again in 2018. Amanda initially was going to file for divorce because she felt as though they were drifting apart, but Bart also filed due to him choosing to be with Kassandra. Since the divorce, Bart and Kassandra have made several claims against Amanda, all of which were disproved by Amanda as well as her labelmates. Bart also disowned his father for the second time due to escalating abuse, but still allows Marge, Lisa, and Maggie to visit. He began the hip hop group cItYb0yZ with fellow rapper JayDee and producer LewisLoud, which broke up in 2018.
