MacGregor's appearance is that of a skinny man in his late twenties with sharp eyes and long and slightly wavy hair which is a mixture of black and blond. He is described as having a bewitching appearance due to the long slits of his eyes and his shallow smile.
He is known to wear a crimson robe with a distinguished design and has a limitless amount of creepy aura coming out of his body. His mannerisms are described as being elegant.
MacGregor appears to enjoy explaining things to others. He also seems to be somewhat sharp-tongue as shown by how he speaks about Surtr Second. Similar to other members of the Lucifer Team, MacGregor is very loyal to Sirzechs and is shown to be afraid of Grayfia.
He was one of the founders of the Hermetic Order of the Golden Dawn and is said to have compiled and translated a book about the 72 Pillars (Lemegeton). His various achievements have made him so famous that anyone involved with magic has heard about him, including the Church. At some point in time, he was reincarnated as a Devil by Sirzechs Lucifer.
