Delta is often described as a musclehead and depicted as excitable and immature, akin to a child. She also refers to herself in the third person. Delta deeply loves her master, even going as far as to hug him on every occasion they meet. She also doesn't mind the idea of mating with him and sharing him with her fellow Shadow Garden members. She and Gamma have had a rivalry over brains versus brawn ever since they were children, but they nonetheless care for one another.
