Megabot

Megabot is a small robot created by Hiro Hamada from the 2014 Disney animated film, Big Hero 6.

Description
Megabot 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.
