Mutation monster | Ninjago

Like other Elemental Monsters, Mutation Monsters first came into existence before the existence of Elemental Masters as a result of the disruption of Source Energy by the Weapon of Desolation. After the First Spinjitzu Master split the Weapon of Desolation into two pieces with an incantation on the Tablet of Desolation, the Elemental Monsters were eventually defeated.

A Mutation Monster was conjured in Umbrasilvis by the Weapon of Desolation. The Explorer's Club dispatched an expedition led by Reginald Slitherbottom to capture the creature, hoping to showcase it as a wonder of the Merged Lands. However, Johnny Courageous, who is secretly a Loyalist, planned to study the Mutation Monster to locate the Weapon of Desolation under the Chief Loyalist's orders.

After the Explorer's Club and the ninja arrived in the village, they encountered the creature. Frak attempted to use his Quake powers but struggled due to the instability of Elemental Powers. As the Mutation Monster escaped, it ran into the Explorer's Club. Wyldfyre intervened but was thrown back by the creature's tentacles. Reginald then tried to ensnare the monster with a net launcher, which initially seemed effective until the creature broke free and prepared to attack him. Frak and Riyu stepped in to help. The Mutation Monster targeted Frak, but Riyu intervened, only to be seized and hit with an energy beam that poisoned him with the Numbness. After Riyu managed to shake off the Monster, Sora created a technological cage to trap the creature before it could strike again.

Later in the Whispering Wood, a Mutation Monster was conjured alongside two Earth Monsters and an Acid Monster as they attacked Lloyd, Arin, and Euphrasia.

A Mutation Monster was conjured in the City of Imperium, attacking the citizens.

Meanwhile, the Mutation Monster in the Whispering Wood attacked Lloyd, Arin, and Euphrasia, gaining the upper hand. Just then, Zane swooped in, landing on the creature and pinning it down, but soon found himself facing the rest of the Elemental Monsters as well. Lloyd received Life Source Energy from the Trees of Life, regaining control of his powers alongside Zane and Euphrasia. The battle intensified as the Mutation Monster unleashed laser beams at Zane and Arin. While they fought off the Elemental Monsters, Zane created a diversion, allowing Arin to use Object Spinjitzu, launching Spinjitzu-powered rocks at the Mutation Monster. Zane then followed up with an Ice attack, destroying the creature's physical form.

To cure Riyu from the Numbness, Sora and Frak needed to extract Elemental Energy from the Mutation Monster and transfer it to him. Upon arriving at the Expanding Frontier, they found the Explorer's Club celebrating, planning to showcase the Mutation Monster back in Ninjago. Sora managed to extract the energy, which seemed to cause it distress. However, when they administered it to Riyu, it turned out to be insufficient. They realized they needed to gather more energy. Meanwhile, unnoticed by the others, Johnny freed the Mutation Monster to study its nature, resulting in the creature running amok aboard the airship.

While Sora was searching for the Mutation Monster in the Expanding Frontier, the creature spotted her and attacked the energy extraction device, only for Sora to save herself and the device. The Mutation Monster then escaped from the ship to the village, much to Reginald's annoyance. Frak and Sora followed the monster to Umbrasilvis, where they found it attacking two Umbrasilvans. Thankfully, Sora and Frak saved them and started fighting against the monster, and the two were then joined by Wyldfyre. During the fight, the creature grabbed Sora, which allowed her to collect energy from its neck with the device. The monster then threw her, the movement knocking the device out of her hand. Thankfully, Freya grabbed it. As Sora left with the device to cure Riyu, Frak and Wyldfyre cornered the creature, only for it to transform into a more monstrous form. The monster grabbed them, only for Gweeg to save them by using a Lariat Launcher. Then, the creature continued to chase Frak and Wyldfyre and eventually knocked them, only to be interrupted by Riyu, who came out of the windmill and transformed into a bigger and stronger form much to the combatants' surprise. Riyu fought against the monster and eventually knocked it down. As he was about to land a final strike on the creature, it disappeared.

Some Elemental Monsters attacked the Arc Dragon of Life, including a Mutation Monster. Later, it chased Arin and Euphrasia, only for Arin to use his Object Spinjitzu to defeat them all.

During the night, some Elemental Monsters attacked the Whispering Wood, including a Mutation Monster. The Mutation Monster tried to attack Arin, but was knocked back by Zane thanks to his Spinjitzu. However, the Monster knocked Arin and Zane back with its tentacles. Then, it focused on Zane and shot a Life beam at him from its eye, only for the Nindroid to dodge the attack and hit its head. The creature then cornered them with the other Elemental Monsters.

When the City of Imperium refused to surrender to her and her Loyalists, Beatrix used the Weapon of Desolation to create a massive army of Elemental Monsters, including Mutation Monsters, which she ordered to attack the city and get through the shield. Cole was on the other side with the monsters and he fought all of them by himself.

Cole, Jay, and Kai were playing a game in the hangar bay when Cole attempted an impressive move but lost his balance, causing all three ninja to fall. Jay accidentally discharged a blast of Lightning toward Kai, knocking him into the containment unit holding the Weapon of Desolation. The impact sent the unit crashing to the ground, where it deactivated as the Weapon of Desolation summoned a Mutation Monster. The creature immediately attacked the three ninja. During the confrontation, Jay's lightning struck the rock ceiling, dislodging debris that fell onto the Mutation Monster and temporarily trapping it beneath the rubble. Cole, Jay, and Kai considered using their Draconus Forms to defeat the creature. However, by the time they did after tricking Lloyd with Zane's help, the Mutation Monster had escaped.

Later that night, everyone in the monastery, except Cole, Jay, and Kai, gathered for a family dinner. Unbeknownst to them, the Mutation Monster was hiding beneath the table. It soon revealed itself, transforming into a larger and more dangerous form before launching an attack against Lloyd and Nya. The Mutation Monster then turned its attention toward Sora's parents. Sora intervened, using Spinjitzu to rescue them from the creature's assault. Meanwhile, Lloyd, Nya, and Zane fought back with their Elemental Powers, but the Mutation Monster blocked their attacks. It continued advancing and striking at the three ninja. Riyu joined the battle and attacked the creature, but the Mutation Monster managed to grab him and slam him into the ground.
