He can also use it to disguise himself as an Earthling to walk among them. When sent to Earth to fight evildoers, he disguises himself as a Japanese man wearing an ordinary suit and fedora hat (looking almost like a police detective), but still uses his "Super Giant" name. His secret identity is not that secret, as he works with the Japanese authorities to help them fight evildoers. He is just as powerful in his civilian form. He also gets along with Earth children, and saves them from danger, as he knows that children represent the Earth's future. After accomplishing his mission, Super Giant always flies back to the Emerald Planet.
