First Omicronian invasion of Earth

The first Omicronian invasion of Earth, also known as The Defence of Earth, was a battle which began after Omicronian Saucers attacked the monuments of the world. The Omicronians demanded that the people of Earth give them McNeal. President McNeal called for all ships of the Democratic Order of Planets to report for duty and assist the Nimbus in attacking the Omicronians. Zapp came up with a plan to concentrate all fire on the Omicronian Mothership which would weaken the other ships. The ships attacked the Mothership and Fry managed to destroy it. Unfortunately what was thought to be the Mothership was actually the. The Mothership destroyed most of the fleet but the Planet Express Ship and the Nimbus survived. The Omicronians kept control of Earth until they saw the final episode of Single Female Lawyer. The next year, the Omicronians invaded Earth again.
