— Ultimate Proto-Bot 10,000
The Ultimate Proto-Bot 10000 (aka UP10K or Protobot for short) is a gigantic robot, and a major antagonist in Club Penguin, although having only appeared a few times. He was defeated by Agent Club in Operation: Protobot.
It was originally created by the Test Bot using drawings from Gary's notebook of blueprints and items around the Island such as the Stage's Ticket Booth, the Inner tube's from the Dock and Beach], the Aqua Grabber cockpit bubble and red tubes, a mine cart, the Boiler Room boiler, and two Dance Club speakers. Later, he became made out of more advanced parts from elsewhere.
