Shadow Dragons Unite

The one-star dragon prepares to deal the final blow to Goku, but before he can, Gohan, Goten, Trunks, and Majuub show up to save him. While Majuub tries to hold off the dragon, Gohan, Goten, and Trunks give all of their power to Goku. Goku absorbs more power than even he thought possible, and even though he's still blind, he can perfectly sense the one-star dragon's movements. The dragon can't even land a punch. Goku fires a Kamehameha wave at the dragon, seemingly killing him. Suddenly, the dragon reappears, having dodged the blast. He sucks up the other six Dragon Balls, which were scattered around the area, and he transforms into Omega Shenron.
