Le dernier allié

The four-star ball flies out of his forehead and becomes Nuova, the four-star dragon. Nuova is no longer on Goku's side, since he was infected with Omega Shenron's negative energy after the dragon ate the ball. Nuova kicks Vegeta aside, and conjures a massive beam. Goku creates a Kamehameha wave, and both he and Nuova turn and fire at Omega Shenron. After being infected with Omega's negative energy, Nuova was flooded with positive energy while inside Goku. Nuova then grabs Omega and encases the two of them in flames. The ball of fire erupts, and it seems that Omega has been destroyed. But when the smoke clears, only Omega is left. Right before the explosion, Omega took cover inside of Nuova's heat-resistant body. Now Omega Shenron is at full power because he has all seven Dragon Balls inside him. (Source: Wikipedia)
