Professor Nigel Shroud (also known as N. Shroud "enshroud") is a mad scientist who is bent on world domination, and secondary antagonist in the series. He is a human and the arch-nemesis of Twilight Sparkle. He is a scientist with an IQ of 300. He dreams of ruling Equestria, but his constant plots to create his N. Shroud Empire are always thwarted by Twilight and her friends.

Personality
N. Shroud is a short-tempered, raucous, pompous, cruel, evil genius who is constantly planning to take over the world. Arrogant and narcissistic, he constructs countless technological wonders in his own image to fuel his massive ego, usually reinforced by his goal of finally constructing the N. Shroud Empire, and doesn't care where it starts.

He has a deep hatred and vengeance of human for laughing at him, and ponies for banishing him.

Although N. Shroud is a villain, he helps Twilight Sparkle when the world is at stake; though the reason is always because he knows there would be nothing left for him to conquer if the world or planet was destroyed. In some of his incarnations, he actually displays a begrudging respect of his arch-enemy, Twilight.

Despite his intelligence, N. Shroud can be very immature, throwing temper tantrums when Twilight and her friends manages to wreck into his plans.

Although N. Shroud is known for childish outbursts when angry, there are a few rare instances where he comes across as stoic and even-toned when extremely aggravated or during very serious situations.

Despite his opposing personality, N. Shroud has rarely shown emotions other than anger or hatred. However, it should be noted that, despite N. Shroud's evil nature, he has shown that he has a soft side of him; that he cares for his robots like Nano, Nobo, Guno, Muno, and Susan.

Although, N. Shroud sees Nobo as his primary punching bag for being so sarcastic and lazy.
