Googol is one of the leaders of the Unseen in Zeropolis. He served Abram Trench, the Grand Shaper of Zeropolis, as his chief technical adviser for many years. He was also a great inventor, creating multiple inventions that benefitted Zeropolis. After that, he saw the wrong in Trench's ways, so he switched sides to the Unseen. A notable invention he created would be the Harmony Bomb, one of the most dangerous weapons within Sidekick.
