Mr. Doom/History

Shortly after founding Poptopia, King Japalka used his Celestial magic to create many, many Geodites. He had a dark secret behind why, however - fifty-two of those Geodites were to be gifted to the hive king of the Poptopian Zombies, Zyveer, in exchange for their vast technology.

Instead of being chained up and experimented on like the other fifty-one, Doom, known as 'Padlock,' was given special audience with Zyveer, who had taken an interest in the doomlock. Zyveer convinced Padlock to be a pawn in his great plan to overthrow the Celestials and take over the surface world. Padlock, naive and desperate to be respected, agreed.

Padlock returned to Poptopia, and quickly rose amongst the ranks of the Celestial court, becoming a royal advisor alongside Gems. All the while, he fed information to Zyveer.

Eventually, Zyveer had lowered Padlock’s guard enough to convince him to let tests be run on him. Often these experiments would leave him exhausted, drained and with a few new scratches, but he was convinced Zyveer was doing it out of love.

Shortly before the plan to overthrow the Celestials was to be put in place, Zyveer ran one final experiment. This experiment replaced Padlock’s hands with sharp, dangerous claws, leaving the Geodite deeply hurt. Finally, Padlock saw what Zyveer and his hive really were, and decided to destroy them.

He took on the new name 'Doom,' and set off a screeching noise in the center of the underground kingdom, which made Zyveer lose his grip on the hive. Then, a series of doomlock went off, leaving the mechanical empire in ruins. Though Zyveer survived, Doom though he had finally killed him and escaped.

Shortly after, he announced to the Celestial court his traitorous intents, to which Akoya responded by trying to appeal to the Padlock in Doom. Enraged, Doom shattered Akoya. After this, the three kings and Mr. Gems fought him off, with the geodite barely managing to escape.

Some time after this, he met and formed an alliance with Queen Eliana Trona Acquisite, and together they overthrew the three kings. For many years, they ruled Poptopia, until Princess Spectrum managed to defeat the queen and restore peace. For his crimes, Gems locked Doom away in a pocket dimension, sealing him with the help of the princess.

After 600 years of stewing in his madness, Queen Acquisite returned, and used her dark magic to free Mr. Doom. He joined her for her brief reign, but was forced to escape when she was defeated. In her final moments, Queen Acquisite told Doom to 'avenge her,' words he took to heart. After this, the spirit form of the queen vaguely guided him to each of the Wicked 7, and eventually they founded the group under that name. Doom plans to resurrect the queen with their help, and take over Poptopia.
