Bowser Jr.

Bowser Jr., known in Japan as Koopa Jr. (not to be confused with Koopa Kid or Baby Bowser), is the secondary antagonist of the Mario franchise and both the son and heir of Bowser. Bowser Jr. first appears in Super Mario Sunshine.
== Personality traits ==
Bowser Jr. seems to be very bratty, spoiled, and mischievous. He is like this because he is raised by his villainous father, who was more or less raised in the same manner by Kamek. He also shares his father's affection for Princess Peach and hatred for Mario, whom he aids in kidnapping and fighting respectively. Despite that, they seem to have a genuine father-son relationship and really care for each other, which is shown in Mario + Rabbids Kingdom Battlewhere Bowser calls Junior on the phone to make sure that he did his homework, implying that he does go to a school of some sort, and later on, Bowser Jr. asks for the heroes' help in saving his father when he was taken over by the Megabug.
In Mario & Luigi: Bowser's Inside Story + Bowser Jr's Journey, Bowser Jr. is initially shown to have very little respect towards the rest of the Koopa Troop and arrogantly believes that they must serve him regardless how he treats them due to his status as a prince. However, over the course of the game he learns that the troop serve his father through love and admiration; things that come from respect. After thinking back to how he treated the Koopalings up until that point, Junior felt sad and remorseful, but Bowser Jr. soon made amends for his past behavior and began showing his minions more care since.
The game also shows that Bowser Jr. does not apparently think about morality when he is helping his father in his goals and instead just does what he, himself, thinks is right. It is also stated that he harbors a lonely side that he does not let other people know about, first alluded to in Mario Party DS. This aspect of his personality was explored in greater depth in Mario & Luigi: Paper Jam with his friendship to Paper Bowser Junior, and the depths the two go to try to keep Paper Bowser Jr. from being forced to return to his own world. A similar depiction of loneliness was also showcased in the Nintendo Switch Online service trailer's Nintendo Entertainment Systemportion, where he attempted to ask his dad to let him play his game with him but then nearly walked away dejected when the Koopa King initially ignored him. He also seems more willing to swallow his pride than his father, such as when he convinced Bowser to accept an invitation to a party after their defeat in Mario Super Sluggers, when he apologized to the Koopalings in Bowser Jr.'s Journey, or when he apologized to and begged Mario to rescue his father from the Megabug's influence in Mario + Rabbids Kingdom Battle.
