SuperMarioGlitchy4 Wiki

The SMG4 cast, also known by fans as SMG4's Gang, or the SMG4 Crew, is a group made up of the main protagonists of the SMG4 series and channel overall.

Originally consisting of SMG4's interpretation of the YouTube Rangers and characters from the Super Mario franchise (such as Mario, Luigi, Bowser and Toad), he later developed his own original characters to add, including but not limited to Fishy Boopkins, Bob Bobowski, Meggy Spletzer, Saiko Bichitaru, Shroomy, Tari, Melony, and the other former members of the Anti-Cast, as well as the less frequent Swagmaster69696969696 and Chris Gordman.

Jeeves also temporarily joined the gang at certain points. Desti, Greg The Alien and Axol were also temporary members/allies before their respective deaths.

Since 2011, they've been up to hilarious, scary, random, and epic misadventures and shenanigans. However, since 2018, they've also been involved in dramatic and rather emotional and serious adventures in story arcs such as The Waluigi Arc, The Anime Arc and The Genesis Arc.

However, despite their major roles throughout Season 10, majority of the main cast was demoted to minor characters by time Season 11 starts, with the main demotions from major to minor being Tari, Saiko, Fishy Boopkins and Shroomy, due to new characters such as SMG0, SMG1 and SMG2, Shadow Meggy, Boyfriend and Girlfriend, and returning characters such as SMG3, Axol (due to his reletively recurring role in Season 10) and Melony. This ends up bringing other members to being full fledged main characters, such as Meggy (due to her formerly on-going character arc following The Anime Arc) and Melony due to her new human transformation and relationship with Axol.


Frequent/Current Members

  • SMG4 - The creator of the videos and one of the two main protagonists of the series. He is a partially amnesiac SMG who resides in Peach's Castle with Mario, often making his bloopers (or playing Minecraft), and gets generally annoyed by Mario (who is apparently his assistant), but he likes him nonetheless.
  • Mario - The SMG4 universe's avatar and one of the two main protagonists of the series. He is obsessed with spaghetti and incredibly retarded. Almost all of the episodes revolve around him and the trouble that he gets the main cast and himself into.
  • Luigi - Mario's younger brother and the deuteragonist of the series. He makes smarter decisions than Mario, but he's still as cowardly as he is in the actual games, if not more so.
  • Fishy Boopkins - A Spike who is a huge anime fan due to his obsession with waifus and who owns many Dakimakura pillows. He first appeared in the Seaside Stupidity two-parter episode, where he saved SMG4 and his friends from drowning in the ocean after their cruise ship was wrecked.
  • Bob Bobowski - A sentient, stupid and annoying piece of trash who speaks in a text-to-speech voice. Mario and Luigi first met him in the sewers of Ganondorf's castle in SM64 Bloopers: Can Ganondorf come out to play?. He's obsessed with fame, money, and getting the most screen-time in his appearances. He was originally used as a humorous punching bag of a character, but later served as the selfish main antagonist of The Rapper Bob Arc. He has since redeemed himself and become a good friend of Mario's.
  • Meggy Spletzer - Formerly a female Inkling, now transformed into a human by The Ink Zuccer 2000, she hails from Inkopolis, but was accidentally captured in a paint bucket in the basement of Peach's Castle and one of the two tritagonists of the series. When Mario accidentally freed her, the two became friends. She competed in Turf Wars with her team, the Splat Squad, until the events of SMG4 Movie: Meggy's Destiny, in which she fulfilled her dream of becoming a Splatfest champion, and she later moved to the Mushroom Kingdom. After she returned from vacation in Port Aurora, she decided on becoming a sports teacher.
  • Shroomy - A young anthropomorphic mushroom and the nephew of Doomguy. He was originally a psychopathic demon hunter but had his brain affected when a bite was taken out of his head in an accident in his youth, leading to him becoming the best member of the boy scouts, with over 300,000 badges to his name. He is very resourceful and (tries to be) helpful to everyone, even strangers. His demon hunter persona joined the Anti-Cast in The YouTube Arc, making him serve as his own doppelganger, but after this arc, he saw a decrease in appearances. Nowadays, he makes occasional major appearances.
  • Saiko Bichitaru - A beautiful but insane love interest from Kevin's School. Boopkins brought her to life one Valentine's Day with Kamek's wand in order to have a real girlfriend, but due to her being mentally unstable and craving attention, their relationship ended in tragedy. She has since redeemed herself with help from Luigi and become close friends with the gang, though she remains a sociopath to most others. She is an expert guitarist and has developed an obsession with KFC's chicken, and she also possesses a giant hammer.
  • Tari - A shy, accident-prone, blue-haired cyborg gamer girl who is obsessed with ducks and lives in an apartment in Onett. She loves video games and is extremely good at them, but outside of them, she hates violence and attempts to avoid it, preferring friendship.
  • Melony - Formerly a sentient watermelon and Anti-Cast member who served as Meggy's doppelganger in The YouTube Arc, she transformed into a human girl after a Fierce Deity Mask was accidentally thrown onto her. She is lazy and spends lots of time sleeping, but is able to create a powerful sword at will upon using the power of her mask. She is also a skilled hacker. She was the former best friend/love interest of the late Axol following after. She's the only former member of the Anti-Cast to become the official member of the main cast.

Occasional members

  • Toad - A cynical and annoying mushroom person obsessed with candy who is annoyed by Mario's antics and spends most of his time standing in one spot in Peach's Castle. Though he was previously a frequently-appearing character, he has almost exclusively appeared in minor roles and cameos since The Anime Arc, with his only notable major roles since then having been SMG4: Mario vs IT 🤡 and SMG4: Nintendo Gets Deleted, though he still resides in Peach's Castle and is also still the main aide of Peach.
  • Bowser - The Koopa King, leader of the Koopa Troop, and one of the two tritagonists of the SMG4 series. In times before, Bowser was always trying to kidnap Princess Peach. Despite them canonically being archenemies, here he is actually one of Mario's friends. He isn't as smart as his Nintendo counterpart and commonly falls victim to his own incompetence. His appearances declined following The Anime Arc, and although he returned for a while in late 2019, his appearances have since seen another decline, and he now only occasionally appears as a member of the gang.
  • Peach Toadstool - The ruler of the Mushroom Kingdom and the castle Mario and almost everyone else resides in. She was the prominent female character in early bloopers until Meggy took over that role in late 2017, hence explaining her recent lack of appearances. She has had a few antagonistic appearances in recent years, such as in Part 1 of The Anime Arc and SMG4: Food Wars, however, she is still often acting like a nagging motherly figure to the gang.
  • Steve - The default avatar used in the world of Minecraft but a character in the SMG4 universe. He's usually friendly with the rest of the members although insulting Minecraft in any way will result in getting on his bad side. He served as a major recurring character in earlier bloopers but stopped appearing with the crew as of Season 8. After SMG4: War Of The Fat Italians 2018, he mostly appears in Minecraft-themed bloopers such as SMG4: If Mario Was in... Minecraft, SMG4: The Minecraft Plague and SMG4: Steve Fights Everyone.
  • Anti-Cast - A group of doppelgängers of SMG4's Gang made by SMG3 to oppose SMG4's Gang in The YouTube Arc . After SMG3's banishment to the Internet Graveyard, all other members have redeemed and became friends afterward.
    • Belle Fontiere - A cyborg gamer girl like Tari. However, she is aggressive and hostile, as opposed to Tari's kindness. She was Tari's doppelganger in The YouTube Arc, but the two later became friends. However, after said arc, she only made a handful of appearances for the rest of Season 10, and she is almost nonexistent in Season 11.
    • Whimpu - A meek Japanese boy who is a computer nerd and simps for female Twitch streamers and anime girls, especially Saiko Bichitaru, who he served as the doppelganger of in The YouTube Arc. He appeared more frequently than the other former Anti-Cast members until Melony's transformation into a human, after which his appearances gradually declined.

Temporary/Former Members

  • Axol - An Inkopolis-born axolotl and manga artist who became famous while living in Japan and who could make anime characters come to life using a magic pen that he invented, the Inkweaver. He met and assisted the gang in The Anime Arc, after which he moved to the Mushroom Kingdom. At first he was a bright character who was looking for inspiration. Over time, however, it became more of a centerpiece of the gang because it motivated the members. Axol has especially helped Meggy to cope with the death of Desti and also encouraged Meggy not to give up no matter what the situation looks like. His Inkweaver broke and he got a red scar on his right eye and tattered clothes in SMG4: The Internet Graveyard. He later got his Inkweaver fixed in SMG4: If Mario Was In... Anime, which resulted in a series of events at the end of the Genesis Arc that led to him becoming possessed by SMG0 (as 'Ax0l') and eventually sacrificing himself (technically committing assisted suicide) in The Final Farewell, when his love interest Melony killed him at his request in order to prevent SMG0 from eradicating the universe.
  • Starman3 - A former friend and ally of SMG4. Due to real-life controversies, he has been removed from SMG4's videos.

He has left the gang as of Meggy's return in SMG4: She's Back!.

He's very unintelligent and often causes a lot of the problems in the series, but has been proven to be helpful in rare instances.

  • Chris Gordman - One of the main protagonists of Guards N' Retards along with his partner Swagmaster69696969696 who used to work as guards at Fresh Spaghetti Tubbie.

After he was banished to the Internet Graveyard by Susan, he became the ruler of the Internet Graveyard and became an unlikely anti-hero.
