In John Scalzi's "The Ghost Brigades," the character of Harvey is depicted as someone who is highly self-aware. He recognizes his abilities and strengths, particularly his talent for creating chaos and destruction. This acknowledgment of his skills highlights both his confidence and the unique role he plays in the narrative, embodying a character who revels in the explosive consequences of his actions.

Harvey's self-identification as "noisy" and skilled at making things "fall down and go boom" reflects a deeper theme of identity and purpose within the story. His characteristics suggest that he thrives in environments that require assertiveness and disruption, paving the way for significant developments in the plot as he engages with other characters and circumstances.
