Gallaher has medium, brown messy hair, amber eyes, and a stubble. He has a slovenly appearance yet fine looks and is slightly indolent. He has an intimidating and stoic appearance and aura but inside, he is truly kind and generous towards anyone unless they get onto his bad side; then it gets physical. Gallagher has a loose red tie, and a white vest over his tight dark grey blouse. He has a muscular and toned body, and due to this, the button on his blouse seems like it might pop off any time.
