Megabot, destroy.
―Hiro Hamada

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 sinister grin. 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, its design is meant to be deceptive; it can split into smaller parts of itself and attach to opponents, taking them apart and utterly defeating them with their own weapons. 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 went back to Bot Fighting with Megabot by his side, without Cass Hamada knowing. One of Megabot's legs falling on Hiro's feet and making him say "ow"; got the young Hamada to activate Baymax. Hiro was fixing his robot's leg, before he realized that Baymax had walked out of the house and went after him.



  • The word "mega", which means huge, is a pun to contrast Megabot's small figure.
  • 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.
