Megabot, destroy.
―Hiro Hamada ordering the Megabot to fight

Megabot is a small robot created by Hiro Hamada from the 2014 Disney animated film, Big Hero 6. It is the main inspiration for the creation of the Microbots.


Megabot is small in size and stature. Its face can alternate between facial expression, ranging from a yellow happy smile to a red demonic grin. This is mostly cosmetic other than to serve as a warning. It was built by Hiro to be used in underground bot fights in San Fransokyo. Although it appears to be an inferior model compared to most bot fighters and has no weapons, its design was meant to be deceptive. It can be easily split into smaller parts of itself and attach to opponents or re-attach to reconstruct itself, then it will use it's deadly agility to rip enemies to pieces.


Big Hero 6

Hiro used it against Mr. Yama and won, and intended to continue using it in more bot fights until he decided to leave this career behind. Afterwards, Megabot's layout and design is used by Hiro to build a new invention, Microbots.

When Tadashi died, Hiro was steadily drawn back into bot-fighting. When preparing to leave for a match, one of Megabot's legs fell on Hiro's foot, which activated Baymax. Hiro was fixing his robot's leg, before he realized that Baymax had walked out of the house and went after him. Megabot is never seen after that.

Big Hero 6: The Series

After Hiro officially goes straight and quits bot-fighting, Megabot is left dormant. It is sometimes stored in Hiro locker at SFIT, and other times at Hiro's bedroom in the Lucky Cat Café. In "The Bot Fighter", Hiro used Megabot as part of his undercover work in Yama's bot-fighting tournament. In during which, Megabot has a rematch against Little Yama, which Hiro is once again successfully in defeating. Later, Trina corrupts Megabot to join her giant killer bot hybrid. Hiro is able to override Trina's programming, however, and uses Megabot to defeat Trina's bot.



  • The word "mega", which means huge, is a pun to contrast Megabot's small figure. However, the potential it has would correctly correspond to "mega".
  • In the Disney app game Big Hero 6: Bot Fight Megabot has three other faces in three different colors, that match the five elements from the game. As Red (on Megabot's battle face) stands for Thermal Powered/Fire and Yellow (for its happy) is for Solar Powered/Light, while its given blue face (Hydro Powered/Water) is for silly, laughing for green (Bio Powered/Plant), and a purple face (Magnetic Powered/Dark) expressing anger.
    • Megabot is also given two lower forms that can be upgraded into the final form that it takes in the film.
  • In Kingdom Hearts III, Megabot is part of the Nano Gear Keyblade's design, passably to reference Hiro. As each part of the Keyblade's design references a member in the Big Hero 6 team.
