Voltron Force (2011)

After the defeat of King Lotor, the team responsible for this victory, the Voltron Force, was disgraced when the Voltron Lions went berserk and were taken out of commission without investigating the cause. Years later, with the team out of action, it seems Voltron is gone for good. However, the team secretly has other plans, which come in handy when new threats revive Lotor to help threaten the galaxy again. Now the team, with a new generation of cadets in training to help them, have brought Voltron back online to protect the Universe.
