Mind Guy

About
Mind Guy is a large, scary demon from the Void and the overall main antagonist of all the Johanis Comics. Mind Guy has plans for world domination, but cannot enact them thanks to Sans and Johanis's Gang being able to defeat him. He has been a threat to all creatures since the beginning of time, and was banished to the depths of Patrickia because of him being a menace to early Patrickian society.

Personality
Mind Guy is usually highly irritable and nonchalant. He will dominate over his acqaintances, and is very evil in general, wanting world domination and all. He commonly will become very large and intimidating, and then scream in the face of his opponent.

Origin
At the beginning of time, a million years before anything existed, all that was around was Mind Guy's father, The Mind Flayer (aka Brain Flayer) and probably some other ancient elementals chilling in the Void. Mind Flayer, realizing his loneliness, chops off his own hand, which forms into Mind Guy, Flayer's "son". The two play cards for millions of years before Patrickia forms from unstable space dust along with the laws of matter and time, so Flayer instructs Mind Guy to go down and conquer this dimension, for him. Mind Guy eventually forms his well-known crew of demons, but is shortly afterwards imprisoned.

Abilities and appearance
Mind Guy can change shape and size for maximum destruction, but generally attains a humanoid shape with a roundish body and four arms. His head has spikes around the edge of it, much like Bart Simpson's. He has no face, but will grow a mouth (and sometimes eyebrows to show expression) if he needs to. Mind Guy also has the power to resurrect the dead, possess people, turn into a viscous blob, and is physically very strong and nearly unstoppable.

Mind Guy has the ability to artificially take anyone into his home, the Oopside Done, either to simply play cards or have a formal chat that almost always ends badly. Speaking of which, Mind Guy also likes playing cards, and is consistently fascinated with threes. He will often drop whatever he is doing and go for any sort of "three" that he will see, including written numbers. In fact, the easiest way to defeat this nearly unstoppable villain is just give him a three and run.

Army
Mind Guy has a fairly sizable demon army, consisting mostly of Demodogs led by the Demogorgon and enormous flesh monsters. While neither him nor any of his monsters were actually present when he attacked Snowball Fight Plateau, he did remotely control Sluggo, who was a flesh demon. While the lot of his army are fighters, some have other jobs or are utterly useless. Together, however, they pack a punch and get the job done.

Sam does...?
Sam is a notable exception, as he has no identifiable task. He appears to be a sort of outcast, living in Bruhkins's mall instead of with the others.

Bruhkins Takeover
In probably the pinnacle point of his career, Mind Guy successfully invaded and destroyed a small town in Indiana called Bruhkins, killing nearly everyone in it. He turned the town into his second base of operations. He even managed to win against Twelve helping the townsfolk and hindering his progress.

This invasion marks a critical event in Johanis history, being Mind Guy's biggest success. Mind Guy generally now uses this event for bragging rights and metaphor use: "Oh, this'll be easier than invading Bruhkins, and now that's really saying something.".

Survivors of the Takeover
As known, there are two possible human survivors of the invasion, each being either ignored or prized by the monsters. They are:

Joyce Blyers
Joyce did not go fight with the other townspeople against Mind Guy, leading to the assumption that she simply stayed home and therefore survived. She probably lives out her days fighting monsters or hiding.

Billy
Billy was a lifeguard and a victim of Mind Guy who was possessed by him. Mind Guy forced him to kill citizens around town, and then build a body for him (which he never used). Billy was seen at the end gloating over the demon's victory with the others, which means he either stayed possessed forever, was killed, or somehow escaped to Earth.

Snowball Fight Plateau Takeover
Mind Guy once tried to infiltrate the main setting of the Johanis-verse, the home of Johanis and his gang. He was stopped by Sans eventually, but not after causing a considerable amount of damage to the town by making certain people invulnerable, and then hurting them in the most gruesome ways possible. He could not physically make an appearance during this attack, and because of this tactical disadvantage he lost. The series of Snowball Fight followed these events.

Relationship with Sans
Sans and Mind Guy have been enemies for hundreds of years, even before Mind Guy killed Twelve. Sans could sense that Mind Guy was evil and up to no good, while Mind Guy simply wanted to enact his plans finally. When things amped up during the Bruhkins takeover, they began to dislike each other even more. The two are now mortal enemies with Mind Guy's dream unfolding and Earth on the brink of death."Mind Guy also kinda stole Cuboid's role as primary antagonist. Not sure about that one. Cuboid's pretty legit actually."
