Dr Nafario

Dr. Joseph Albert Nefario, most commonly referred to as Dr. Nefario, is a character in Season 3 of Chapter 1 and a major character from the chapter 1 finale onwards. Originally, Nefario worked for Gru for many years after being an independent scientist in contact with the Dreamy Zone Foundation, though when Gru retired from villainy Dr Nefario returned to the Dreamy Zone Foundation permanently. Nefario is know for his various "principals" and inventions, he is the main scientist at the base and often a voice of reason.

Appearance
Dr. Nefario dresses like a stereotypical mad scientist. He is generally elderly, mildly overweight, and is apparently hard of hearing (though in ZNA he has since fixed his hearing), which frequently gave him trouble with initial consonants. He is always seen with his labcoat, gloves, and trademark goggles, and he wears either pants or pajama bottoms with a plaid pattern. His hair, what little there is of it, is longish and faintly unruly.

He also owns a suit, and once wore a prison jumpsuit when he and the gangers were arrested.

Personality
Nefario is a respectful, kind elderly ganger. He, much like the rest of the gangers, has a wacky sense of humor and obliviousness to his occasional wack actions. Nefario enjoys being busy and loves working in the lab with Vance, Dave, the minions or his scientists. Nefario is shown to enjoy Wendys. much like the other gangers. He has a high level respect for Zeamy, being the only ganger who consistently calls him "boss". Nefario is also very handy with using and designing weapons.

On occasions, despite his genius he can occasionally have things slip past him. He was unaware of Kumin listening in on the gangers in the testing room and he didn't have a back up plan in the event Scarlett and her crew got the upper hand on the gangers.

Zeamy
Nefario was a constant associate of the Dreamy Zone Foundation for years, so he and Zeamy are very close friends. Nefario holds Zeamy to the same level of respect as Gru, Nefario often refers to Zeamy as "Boss" and rarely makes derogatory remarks towards him like the other gangers do. Nefario is always willing to help Zeamy and the gangers with his various inventions and principals. Nefario, much like Kumin, integrates himself well with Zeamy and his gangers despite not being traditionally hood.

Zeamy seems to share equal respect for Nefario, often calling him "Doctor" and treating him with respect. However at times Nefario has also been known to get on Zeamy's nerves, like when Nefario and Buzz got drunk on their way to meet the Avengers. Despite this, Nefario and Zeamy have a healthy working relationship and friendship.

Vance
Nefario sees Vance as someone to take under his wing. Vance often helps Nefario with his various principals, the two have grown to become very good friends. Nefario helped Vance with his quirk troubles and often looks out for Vance more often than not.

Gru
Nefario is Gru's closest and most loyal friend who always comes to his rescue. He has a very high respect for Gru and even believes he is the greatest villain in the world, but he often doubts his abilities and motives. When Gru turns over to beign good, Nefario eventually ajusts to him and the girls and continues to work in the lab witht he minions on non-evil projects. Nefario and Gru don't interact much in ZNA, though they still appear to be good friends.

Dave
While Dave is overall an outcast to the gangers, Nefario and him have a healthy working relationship due to their history with Gru. Dave often helps Nefario with his various inventions and studies. It can be assumed that Nefario is Dave's only friend besides the other minions.

Unfortunatly, After Dave's out burst on the 16th of January, he was removed from the foundation 2 days later and it can be assumed that Nefario no longer likes Dave.

David
David and Nefario despite having no prior relations, are good friends in present time. David much like Dave and Vance, assists Nefario though David accompanies Nefario more as a friend above anything else.
