Ep 4. Phantoms

In Legion of Super Heroes season 1 episode 4, titled "Phantoms," the team is faced with a new challenge when they come across a group of lost travelers who are being haunted by a mysterious entity on the planet of Trom. The entity, called the Phantom Zone, is a powerful force that can manipulate reality itself, making it difficult for the Legion to get a handle on the situation.

As the team searches for a way to confront the Phantom Zone and help the travelers, they begin to learn more about the entity and its strange powers. They discover that it has the ability to create illusory objects and creatures, and that it feeds on fear and negative emotions. This knowledge leads the team to realize that the key to defeating the Phantom Zone may be to remain calm and avoid giving in to its tricks.

While the Legion races to help the travelers and defeat the Phantom Zone, they also have to contend with a group of rebels on Trom who are looking to overthrow the planet's government. The rebels have their own reasons for wanting to take control, but the Legion soon discovers that their motives may not be entirely pure.

As tensions mount and the stakes get higher, the Legion must work together to overcome the challenges ahead. They are aided by a few unlikely allies, and they begin to unravel the mystery behind the Phantom Zone and the rebels' true intentions.

As the episode comes to a close, the Legion emerges victorious, but not without suffering a few losses along the way. They return to their base with the knowledge that they have faced some of the most difficult challenges yet, and that they will need to stay strong and united if they hope to survive the obstacles ahead.
