Bart Simpson (seasons 16-30)

Bartholomew JoJo Simpson, nicknamed Bart is the tritagonist of the long-running American sitcom, The Simpsons. He is the mischievous and rebellious eldest child of Homer and Marge Simpson, and the older brother of Lisa and Maggie. Sadly, he got flanderized in Season 16.

Bad Qualities

 * 1) In seasons 1-15 and seasons 31-present, he was rebellious yet likeable. In these seasons, he is just nothing more than a spoiled brat in a rather manipulative and malicious way.
 * 2) Ever since season 16, he became a downright sociopath, but not in a way of waiting domination, just throw antics to either the over-the-top level or to an excessive degree.
 * 3) He can get extremely selfish, similarly to Mr. Krabs.
 * 4) He terrorizes Seymour Skinner and Edna Krabappel on many occasions.
 * 5) While he got his comeuppance, he intentionally exposed himself naked to the public in The Simpsons Movie.
 * 6) There are a few episodes where he is at his absolute worst, these include episodes like "Love is a Many Strangled Thing" for example.
 * 7) Even when he isn't being unlikable, he can be treated like a massive butt-monkey at times, such as in "On a Clear Day I Can't See My Sister", "The Boys of Bummer" and especially "Bart vs. Itchy & Scratchy".
 * 8) *Speaking of "The Boys of Bummer", his character was basically nothing more than just a punching bag in the episode, in fact, he was bullied so much that he even attempted to commit suicide in that episode.

Good Qualities

 * 1) He used to be a good character before Season 16, and he has improved in Season 31.
 * 2) He does get his comeuppances after his antics go way too far.
 * 3) Similar to his dad, there are still episodes where he is at his best.
 * 4) His catchphrases, including "Don't have a cow man!" and "Eat my shorts!" are still funny and memorable.
 * 5) Depending on your view, he, along with Homer, is still memorable and/or likable.
