The South Park Game Wiki

The legendary Mysterion is different than his fellow superhero companions in one important way, he actually has a superpower. He can never die. Known by most as unassuming Kenny McCormick during the day, Mysterion might just be the hero South Park needs to set right the growing evil that lurks in the shadows.[1]

Mysterion is the superhero alter-ego of Kenny McCormick in South Park: The Fractured But Whole. He fights in melee range and is a re-born Netherborn. When killed he can assume the form of Dead Mysterion, giving him new abilities, and he can no longer be attacked, despite being shown with 50 health.

For Mysterion's role in South Park: Phone Destroyer, see Mysterion (Phone Destroyer).

Appearance and Personality

Mysterion's costume is primarily two shades of purple. The body suit is lighter with a green 'M' in the center of the chest. His cape and hood are a darker purple. He wears a black eye mask and military green gloves. Attached to his hood above his forehead is a green question mark. It appears to be attached to the hood via a spring. His boots are brown.

Personality wise, Mysterion acts in a lawful manner, acting what's best for the Freedom Pals, even to the extent of being a vigilante savior for South Park. He does rue his powers as a curse though, stating that it heavily weighs on him.


Mysterion sided with the Freedom Pals during the civil war, however, he also took the problems of the town seriously and tries to fight crime.

Mysterion made his first appearance in Civil War, accusing the Coon for his biased view on different superheroes. afterwards, he battled the Coon and Friends with Wonder Tweek and Tupperware, out-numbered and outmatched, he was defeated.

He showed up again in Civil War 2, demanded the return of Doctor Timothy's phone, and he asked the Coon and Friends to stop investigating the Chamber of Commerce. Only greeted by the fake news created by the Coon that they already had a connection with Netflix. Doctor Timothy called the Coon's bluff after raping his mind, enraged, the Coon and Friends had the second battle with the Freedom Pals. At the start of the battle, Mysterion suggested the Coon Friends give up as they are "outmatched", However, he was defeated again along with his fellow Freedom Pals, even with many kindergardeners on their side.

When the New Kid entered the Freedom Pals' base with Professor Chaos, Mysterion ambushed them and assumed that they were here to spy on Doctor Timothy's Secret work. Just as they were about to destroy the two intruders, Doctor Timothy appeared and gave a chance to the New Kid to prove the purity of their intentions. Mysterion guarded the working room, preventing anyone from going in. After the Shady Acres' mission, Freedom Pals accepted the New Kid as one of them. However, Mysterion still guarded the room, keeping the New Kid from going into the room to observe Doctor Timothy's work.

On the third night, Mysterion led the New Kid to the police station, on the way, he expressed his intentions to save the town, and his empathy with the New Kid as they both had super powers (though he falsely thought that the New Kid's ability was the farting power alone).

Having reached the police station, Mysterion ordered the New Kid and Toolshed to cause a diversion, before the Coon and Friends arrived and gave him a shock. Hesitating, Mysterion agreed to the plan to have Coon and Friends cause the diversion. When the New Kid reached the top floor, followed by all members of the Coon and Friends Tupperware, and Mysterion, Mysterion called all of the Freedom Pals to the top floor, embracing a Jared boss fight.

Having defeated Shub-Niggurath, Coon and Friends left the scene. Surprised, Mysterion caught up alongside other Freedom Pals. Having learnt that the New Kid played a trick on them, Mysterion became furious, attempted to destroy the New Kid. However, Doctor Timothy manipulated Coon and Friends to do the work, so Mysterion stayed, encouraging the manipulated to destroy the New Kid.

After the defeat of Doctor Timothy, Mysterion revealed the true intentions of Doctor Timothy, creating a plan that is fair and inclusive. Then he accused the New Kid for attacking the Doctor, completely ignoring the fact that the Doctor assaulted the New Kid in the first place.

The next day, Mysterion called all the Freedom Pals to base, showing the severe damage that had happened to Doctor Timothy's franchise plan.

Mysterion then worked with other superheroes to catch the Coon, went to the lab, he also went to the far future, as well as the past.


A reborn-again Netherborn, Mysterion possess power and knowledge man was not meant to have. In times of desperation he can assume his ultimate form: Dead Mysterion. - In-game character description

Mysterion is unique among the playable characters, in that he has two distinct "forms". In his normal state, he uses powerful melee attacks that draw foes towards him, setting them up for punishment from his allies. Compared to other melee-focused heroes, his health is quite low...but this factors into his unique playstyle.

If Mysterion's health is depleted (whether by his enemies, status, or his own Ultimate), his body is consumed by rats (preventing revival by normal means) as his spirit emerges as "Dead Mysterion". In this form, he gains an all-new moveset focused on debuffing his enemies with Chill, Defense Down, and Confuse. He also has a new Ultimate that allows him to return to life, healing allies near himself in the process.
