None of the dragons that appear in Dragon Ball GT are more feared than the near-invincible ultimate enemy known as Omega Shenron. Initially arriving on the scene as Syn Shenron, a shocking power-up during an intense battle helped the beast rise to even greater levels of strength. Compared to his previous form, Omega Shenron's power was unmatched and incomparable to anything seen before in the Dragon Ball universe, serving as the biggest threat to humankind.
