Ep 27. The Buried Castle

In the episode "The Buried Castle" of Voltron: Defender of the Universe season 1, the team receives a transmission from an old friend named Coran, who requests their help in uncovering a lost castle buried beneath the surface of a barren planet. The team, consisting of Keith, Lance, Pidge, Hunk, and Princess Allura, eagerly accepts the challenge and sets off to find the castle.

Upon arriving at the planet, the team begins their search for the buried castle. Pidge manages to locate the castle's entrance, and the team enters to find themselves in a maze-like structure. As they journey deeper into the castle, they encounter several traps and obstacles, including a mysterious black fog that seems to sap their strength.

As the team continues to explore, they encounter a group of giant robots that are guarding the castle. The team fights back using their Voltron lions, but they soon realize that the robots are too powerful for them to defeat alone. They retreat and regroup, coming up with a plan to incapacitate the robots by burying them under a pile of rocks.

With the robots taken care of, the team continues their exploration of the castle and discovers a room filled with ancient artifacts. Princess Allura is excited to find a relic that belonged to her father, King Alfor, but she is soon overcome with grief as memories of her lost family flood back to her.

As the team continues to search the castle, they stumble upon a room containing a powerful energy source. Before they can investigate further, they are attacked by a group of alien invaders who are also searching for the energy source. The team fights back, and the invaders retreat.

The team realizes that they must stop the invaders from getting their hands on the energy source, as it could have disastrous consequences for the universe. They track the invaders to their spaceship and engage them in a final battle.

After defeating the invaders, the team returns to the buried castle and manages to activate the energy source. As they do so, they realize that the castle is not just an ordinary structure, but a powerful weapon capable of destroying entire planets. They decide to keep the castle a secret to prevent it from falling into the wrong hands.

The episode ends with the team reflecting on their adventures and looking forward to their next challenge. The Buried Castle has provided them with a wealth of knowledge and new experiences that they will use to face whatever comes their way.
