Character portrayal Jenni Lada of
Siliconera described Bowser Jr.'s role in the ''Bowser Jr.'s Journey'' game as an enjoyable protagonist. Lada felt that he often draws attention with his playful and bratty behavior, motivated by a desire to make his father proud. She stated that he can be mischievous and annoying at times, but is not truly evil, and the game shows him trying to do the right thing. Lada considered Bowser Jr. to be determined and impatient, often insisting on his own way, but showing moments of innocence and naivety that could be amusing. She felt that Bowser Jr.'s "my way or the highway" approach suited the game, which she believed sometimes feel like the player is brute-forcing their way through it, particularly since he realizes that his approach is not effective and would disappoint his father. Ethan Gach, writing for
Kotaku, stated that after playing ''Bowser Jr.'s Journey'', he felt the game meaningfully fleshed out Bowser Jr.'s characterization. He observed that the story presents Bowser as a flawed parent attempting to balance the responsibilities of ruling a kingdom with raising a troubled child, while also depicting Bowser Jr. facing challenges following his father's sudden absence. Holly Green, writing for
The A.V. Club, criticized the depiction of Bowser Jr. in ''Bowser's Fury'', observing how he had to ask his main enemy, Mario, for assistance in order to reach his aggressive father in the narrative. She said that this kind of storytelling is disturbing for a children's game and conveyed that this was not the first time she had felt worried about Bowser Jr., citing a possibility of Princess Peach being his mother, which she described as "logistically is horrifying in more ways than one". She concluded, "I'm rooting for Bowser Jr. No one should have to consult an adult, much less one of their mortal enemies, to reign a parent with an anger problem. You're a brat, Bowser Jr., but you deserve a better father". In November 2025, the design of Bowser Jr., particularly his bloodshot eyes in
The Super Mario Galaxy Movie, drew attention.
Kotaku journalist Kenneth Shepard, commenting on the film's promotional trailer, observed that the depiction of Bowser Jr. featured bloodshot eyes, contrasting with the franchise's usual stylized designs. Shepard suggested that the exaggerated eye design may serve as an artistic device reflecting fatigue or emotional instability, and noted that viewers found it unsettling. He questioned whether the design would remain unchanged before release, comparing it to the pre-release redesign of
Sonic the Hedgehog in
Paramount Pictures'
2020 film adaptation.
GameSpot journalist Lan Pitts expressed similar concerns. Jenna Anderson of
The Mary Sue stated that she possesses maternal instincts towards Bowser Jr. and selects him as her main character to play throughout the
Mario franchise games. Ever since the release of 2023's
The Super Mario Bros. Movie, Anderson said that she was eagerly waiting for Bowser Jr.'s casting in
The Super Mario Galaxy Movie, with
Jack Black's "over-the-top" voice of Bowser in consideration, fan-made concepts for Bowser Jr.'s voice included personalities like
Kevin Hart,
The Rizzler, and
Tim Robinson. In contrast, she said that
Benny Safdie was a "great" and "memorable" selection for Bowser Jr., mentioning his
filmography and involvement in the
Oscars. In coverage by
VG247, writers Hirun Cryer and Nadia Oxford inspected Bowser Jr. in
Mario Tennis Aces, focusing on his playstyle and characterization. Cryer was highly critical, classifying him as frustrating to compete against and finding fault in his design, especially with his reliance on a mechanical assistant during matches, which he argued makes his role feel less direct. Oxford, however, took on a more positive view, referencing Bowser Jr.'s personality and his repeated desire to impress his father and noted that their interactions added charm and humor across different appearances.
Competitive play In July 2018, Ian Walker of
Kotaku reported on significant competitive backlash toward Bowser Jr. in
Mario Tennis Aces, where many players considered him the most overpowered character on the roster. Within weeks of the game's release, online discussions were filled with complaints, matchup advice requests, and, in some cases, refusals to play against Bowser Jr. players in online matches. Competitive player Jonathan "Accel" Conaway stated that Bowser Jr. "essentially has every good trait in the game with nothing to offset it", arguing that the character had no clear disadvantage in neutral play. As a defensive-type character, Bowser Jr. possessed exceptional court coverage, with a reach that allowed him to return shots without diving, enabling stronger standard returns rather than weaker recovery hits. Although other character
Waluigi shared the defensive classification, players widely viewed Bowser Jr. as superior due to his particular combination of attributes, including strong shot angles that could push opponents out of position, efficient super meter gain, and the ability to drift toward incoming shots while charging without sacrificing much movement speed, similar to hovering characters like
Boo and
Rosalina. His effective use of the "Trick Shot" mechanic further reduced risk, allowing him to recover from disadvantaged positions and quickly regain control of rallies. Following this controversy, Bowser Jr. was given multiple significant nerfs that weakened his competitive viability, as reported by Emma Kent of
Eurogamer.
Miscellaneous In 2017,
Game Informer Elise Favis notified about a
YouTuber called "TheDominoKing", known for showcasing
domino effect setups usually for video game or pop culture-related material. He also created a setup for Bowser Jr., according to him, the setup required 5 days of effort and involved a total of more than 23 thousand
dominoes. In the same year, an
internet meme originated from
Nintendo Switch's parental control advertising, depicting Bowser as an overprotective father, covering Bowser Jr.'s eyes whenever inappropriate content comes on-screen.
Mic Tim Mulkerin said that this inspired multiple
4chan users to utilize this meme format in unique ways. In June 2023,
GamesRadar+ journalist Jordan Gerblick reported an apparent inconsistency in the ages of Bowser and Bowser Jr. after Nintendo published an instructional video on its
YouTube channel. The video, which demonstrated how to create a Nintendo account, used Bowser and Bowser Jr. as example profiles and displayed their birthdates as February 5, 1989, and March 3, 2010, respectively. Based on these dates, Bowser would be 34 years old, and Bowser Jr. would be 13 years old at the time of publication. Gerblick noted that the figures appear inconsistent with the characters' established debut appearances in the series, as Bowser first appeared in
Super Mario Bros. (1985), and Bowser Jr. debuted in
Super Mario Sunshine (2002). The discrepancy prompted discussion about the internal chronology of the
Mario franchise. However, Gerblick suggested that the displayed dates were likely arbitrary, attributing it to Nintendo's lack of attention to such details. In September 2025, Josh Coulson from
TheGamer reported a toy leak suggesting that Bowser Jr. is in
The Super Mario Galaxy Movie. Coulson mentioned that tie-in merchandise is typically made in advance of a film's release, and that an image circulating online showed an unfinished action figure of Bowser Jr. by
Jakks Pacific. Although the figure lacked its detailing, the character remained identifiable. The leak gained additional attention after the image was
copyrighted by
NBCUniversal. Later in November, when Bowser Jr. was confirmed for
The Super Mario Galaxy Movie, Coulson reported another new discussion appeared online that was related to the
Marvel Comics character
Prowler, especially for his theme. Critics argued that the sound effect used for Bowser Jr. in the film's promotional trailer sounded similar to that of Prowler's theme in
Spider-Man: Into the Spider-Verse. The musician
Daniel Pemberton, who was involved in making music for
Into the Spider-Verse, also noticed the familiarity between the sounds. == Further reading ==
