Metal Siege is a flipper bot made from a Hexbug Bronco. It was originally made back in 2018 as a wedge bot, before quickly being redesigned using the stock Bronco flipper mechanism to make flipper, but received a redesign in 2019 that incorporated a Bronco flipper attached directly to the main flipper mechanism, the first of its kind (I think).
Metal Siege competed in every early era Robot Khaos season (1-3) before being disassembled, as its flipper mechanism had broken from stress. The bot made a comeback in 2022 with a new design, but wasn’t able to come back until 2023 due to complications with the drive and weapon.
The significance of Metal Siege comes from its long history and consistency, being one of the most powerful Hexbug flippers in the community and boasting a very solid record through its channel appearances, and is a favorite to make a run at a title in Robot Madness. Even if Snowblind kept it from earning a title in 2 of its 3 seasons in Robot Khaos, Snowblind can’t stop it from earning a well deserved place in the Hall of Fame.
