Before Davis even applied pressure to the trigger of his hand cannon, the Squalon already unfolded its helmet and encased the wearer's head.
A powerful round smacked against the visor of the Squalon shortly afterwards. It deflected and pinged off the incredibly resilient surface without leaving behind a single scratch!
To his credit, Davis continued to pull the trigger even after he fired the first round. The powerful hand cannon in his grip didn't possess a high rate of fire, but the mech technician-turned-traitor fired as fast as his sidearm allowed.
As the Squalon's helmet continued to ward off the incoming shots without fail, Ves even had the time to admire Davis' trained shooting posture and accuracy. By far most of the rounds his helmet!
