Monroe Connery Boyd Carlyle McGregor Scott V (Monroe for short, voiced by Carlos Alazraqui) is an enchanted pug that speaks with a Scottish accent. He is quite educated in the world of magic, having been alive for several centuries and assisting each Te Xuan Ze for nearly that entire time. Despite his knowledge, his ability to actually use magic or magical devices is fairly limited, due to his lack of grasping hands or opposable thumbs (according to Ray Ray, he uses this as an excuse for "everything").
Monroe is a magical talking dog, allowing him to be understood by those who can see through the magic barrier. Anyone else listening to him will only hear barking. He is also lactose intolerant. Monroe has an elderly dad who used to be advisor to Te Xuan Ze of past as well, although it is unclear at what exact time he was the advisor as it seems that Jasmine is well-acquainted with him as well.
Extended Longevity: He is several hundred years old and ages much slower than normal dogs or humans.
Magic & Mysticism: Monroe is capable of using magic, spellbooks, and creating potions to aid the Te Xuan Ze whenever he can.
Intelligence & Cunning: Monroe is a battle-experienced strategist and brilliant magics engineer as well as a researcher of magic and its history.
Trivia
He is a main character.
In "Monster Con" and "Magic Takes a Holiday", he is seen eating chocolate which is lethal for dogs. This could be either a mistake from the producers or because he can actually eat it with no harm.
In "Welcome Bat Otter", we find out that Monroe has been taking pottery classes.
In "Water We Fighting For?" we find out Monroe is 600 years old. June asks why he wears tanning lotion if he has fur to which he replies how else is he keeping up his looks. (Look at me! I'm 600 years old and don't look a day over 575!)
