Baldroy is a tough-minded, level-headed American veteran.[9] Like the other Phantomhive servants, he is fiercely loyal to Ciel Phantomhive and deeply respects Sebastian Michaelis.

Baldroy takes charge of the other servants whenever Ciel and Sebastian are not around, such as when he coordinated an attack on the first-string circus members.[10] He remains calm and sensible even during dire situations and focuses on how to proceed rather than succumb to his emotions.
