Giant Boo is a Boo that is a little bigger than Bowser.
Story
Edit
Professor E. Gadd created him by accident at Luigi's Mansion, where King Boo floated into his machine to stop him. When the machine exploded, it created Giant Boo.
 This article, Giant Boo, is short like Toad. You can help Super Mario Fanon by expanding it as big as Bowser. |
