The guard is a guard at the Jasper Museum. He is incredulous to the statements of children but will accept government authority at face value.
The guard was on duty guarding the museum one night when the alarm sounded. He failed to notice the Transformer battle raging outside, but he did discover that a sphere was missing. He then caught and detained Miko trying to exit through a delivery entrance. While waiting for the authorities to arrive, the guard questioned Miko. He listened to Miko's story about researching her history report until Agent Fowler arrived and took custody of her.
