Fitz grew up in Scotland, where he developed an early interest in engineering and technology. His relationship with his father was tumultuous, with his father often being dismissive and emotionally distant. This strained relationship left Fitz seeking validation and approval, which contributed to his drive to excel academically and professionally.

Academy, where they were known as the inseparable duo "FitzSimmons."

His determination to overcome these challenges highlights his resilience and deep love for Simmons, motivating him to push through adversity.

Fitz's character arc also explores themes of duality and inner conflict, particularly evident in the Framework storyline.
