Blank Robots, also known as Blank Heroes, are mindless drones made in Hero Factory's Assembly Tower. Unlike other heroes, they don't need Quaza cores to power them.
Hundreds of these Robots were used by Mark Surge, who was corrupted by a Brain. Many were destroyed by the Alpha 1 Team and the rest were deactivated by Surge after Breez removed the foreign Brain.
- Since they don't need Quaza cores, it is unknown what powers them.
- These characters run contrary to a previous episode, where Mr. Makuro states that Heroes are made from scratch.
