The Bull Clones were an army of mechanical bull robots that were created by Red Son. They worked for the Demon Bull Family until they were possessed by the power source that the Demon Bull King discovered.
The Bull Clones (except General Ironclad) wait for Princess Iron Fan and Red Son to free the Demon Bull King until they watch Bob attempting to pull the Golden Staff off the mountain but failed. After Red Son was able pull the Golden Staff off, the Bull Clones cheered while Bob looks down in dismay. However, when MK inadvertently used the staff, the Bull Clones attempt to take it from him but were overwhelmed when MK used the staff again.
At the Flaming Foundry, the Bull Clones made more of themselves or talked to each other.
Later, the Bull Clones attempt to stop MK's Team from entering the city but failed to do so.
The Bull Clones break into the Weather Station to help Red Son take control of the city's weather. When MK and his team attempt to stop Red Son, the Bull Clones captured them after MK accidentally injured Mei and Sandy, as he couldn't control his his powers.
However, after the Monkey King limited MK's powers, the Bull Clones were defeated.
While spying on MK's Team, General Ironclad contacts Princess Iron Fan and was ordered to steal the Dragon Blade for her.
Later, when Mei was preparing the sleepover, General Ironclad steals the Dragon Blade and starts destroying the Dragon House until he loses the Dragon Blade. When Mei was able to take the Dragon Blade back, she uses it to defeat General Ironclad.
While Red Son was taking with Princess Iron Fan, the Bull Clones were digging up the tomb the Demon Bull King discovered.
The Bull Clones continued to dig up the energy source the Demon Bull King found until one of them was able to dig up the tomb. However, once the tomb was opened, the energy source took possession of the Demon Bull King as well as the Bull Clones.
During the Battle of the Flaming Foundry, the Bull Clones attack MK's Team to prevent them from reaching the Demon Bull King.
After MK freed the Demon Bull King from the mysterious whisperer's possession, the Bull Clones were freed from the possession as well, but were deactivated as a result.
The Bull Clones were dark gray and purple robots with dark gray armor that showed the Demon Bull Family's insignia, as well as magenta arms and horns and dark gray hands and heads. They also possessed a golden ring on each of their nose.
When possessed by the power that the Demon Bull King discovered, the Bull Clones gained mouths and the orange coloring on them turned blue.
