E-77 Lucky is a ridiculous looking E-Series robot, created by Eggman to find the 7th Chaos Emerald in Season 1. His main body is a large bell with two visible eyes and the number 7 painted on in red, and he is covered in good luck charms, including 4 leafed clovers and rabbits' feet, he is exactly 100cm (3ft 3in) tall and weighs 100kg. Lucky was created because Eggman believed that with a little more luck, he could obtain all seven Chaos Emeralds. At first, Lucky seems to have bad luck, and he is constantly falling down and getting into trouble. But later he is revealed to have good luck when he finds the seventh Chaos Emerald. After the first season, Lucky isn't seen again for a while, until the Emerald Tournament, where for a few rounds he remains on a good luck streak and continues to win by default, but finally loses against Emerl when he falls down during their fight. Lucky's only form of communication is through beeping, similar to R2-D2 of Star Wars fame.
