The Ultimate Proto-Bot 10000, or UP10K for short, is a gigantic robot who terrorizes the island in the MMO (Massively Multiplayer Online) game, Club Penguin. He was built by the Test Bots, who used drawings and blueprints they stole from Gary the Gadget Guy. UP10K later refined himself to make himself look much more menacing. He wants to rule Club Penguin, and is worse than Herbert P. Bear. He is an enemy of the EPF (Elite Penguin Force), which is Club Penguin's secret agency and protectors.
Club Penguin: Elite Penguin Force
In the video game Club Penguin: Elite Penguin Force, UP10K makes his first appearance as the main antagonist in the game. He kidnaps Gary and the Elite Puffles and your character must go around the island fighting UP10K, and the player will eventually defeat him on Tallest Mountain, while rescuing Gary and the Elite Puffles.
In the mini-game "System Defender", UP10K returns, revealing that he has been rebuilt. The EPF find out that he had been rebuilt by Herbert P. Bear. Then, they tried to ruin the Earth Day Party of 2012 with the Test Bots, but ultimately were defeated by the EPF. After that, Herbert and UP10K got into a disagreement. Unlike Herbert, UP10K it didn't want to defeat the EPF, it wants to permanently destroy them. So, Herbert and UP10K broke their alliance, and tried to take over the island in their own seperate ways.
Marvel Super Hero Takeover 2012
In the Marvel Super Hero Takeover of 2012, UP10K was powered by a meteorite that had struck the island. The meteorite gave all penguins superpowers. UP10K took advantage of this situation, and built the Destructobot to destroy the island. Some of the penguins with powers joined UP10K and became supervillains, while the rest teamed up with the EPF to become super heroes. In the end, UP10K and his Destructobot were defeated, the meteorite's power faded (causing all the penguins to lose their powers), and all the penguins who become supervillains had their memory wiped.
Marvel Super Hero Takeover 2013
In the Marvel Super Hero Takeover of 2013, energy crystals grew around the island, giving all the penguins superpowers again. Again, some became superheroes and some became supervillains. UP10K returned, and he ordered the Super Villains to create their own robots, and attack Club Penguin. When he is finished attacking Club Penguin he plans to turn all the penguins into robots, and become the leader of a new technologically advanced metropolis called Robotopia, to replace Club Penguin Island. He fails in the end, and, yet again, all the supervillains memories are wiped.
UP10K returned in the future more powerful then ever. He built microbots, small robots that act as his minions. He also threatened to destroy the future island if Gary didn't tend to his demands. He wanted to steal EPF technology to rule the island in the past. The EPF (Extra-Planetary Federation), which is the future version of the EPF, was unavailable because they were rescuing aliens on Upzar II. In order to help defeat him, players were able to use Gary's time trekker to go the the future and use robotic mechs. Players found him in orbit, and managed to defeat him, and he exploded.
Lucky's Elite Puffle Training
Lucky, who is a gold puffle and elite puffle, was going with PH (Puffle Handler) and the rest of the elite puffles to train in the wilderness. UP10K rebuilt Destructobot and gave him the ability to speak, and sent him to kidnap PH and the elite puffles (excluding Lucky). He then put Brain-Boxes (helmets that control minds) on them. Lucky used Flit's flute to deactivate the Brain-Boxes, and then used it to cause UP10K and Destructobot to malfunction.
