The Darkest Day

After a year of space travel, the two Saiyans, Vegeta and Nappa, arrive on Earth. To celebrate their arrival, Nappa completely destroys East City with ease by creating an energy blast. Vegeta chastises Nappa, as he could have also destroyed the Dragon Balls. Sensing their power, the Z Fighters mobilize for an attack. The Saiyans search for any large power levels with their scouters, and they head toward Piccolo and Gohan. Just when Krillin shows up to help, the Saiyans also arrive. Piccolo learns that he is a Namekian because Vegeta recognizes the green skin that is typical of Namekians. Yajirobe knows the threat as well, but instead of stopping them, he poses as the leader of Earth's Special Forces to get free food.
