Shaggy

Shaggy is the strongest form of existence in the universe. He served as the president of Unite States from 1897 to 1901. In his election, his opposing candidate was said to have died of heart attack from seeing him directly. He wanted to have Scooby-Doo as his vice president, but upon realizing that his presence might be harm to his best friend, he decides to have some guy named Christoper Columbus to be the sacrificial pun. He used 0.00000000000000000001% of his powers to grant immortality to Columbus, making sure he would stay alive during the duration of his term.
