Buck Rogers in the 25th Century

Buck journeys through a space warp into another universe, where he discovers that the peaceful planet Pendar is being threatened by the sinister war witch Zarina. The Pendarans enlist the aid of Buck and Princess Ardala, who had followed Buck through the space warp, and an unsteady alliance between the humans and Draconians is formed as Buck leads a combined fleet against Zarina's battlecruiser.

Buck attempts to free a peaceful planet from the powerful grip of an evil warlord known as the Traybor. He leads a band of men into Traybor's fortress in the hope of freeing the women the alien has kidnapped, but Traybor has a few special powers that may end Buck's career at any moment.

Buck is haunted by the appearance of a young woman who bears a striking resemblance to Jennifer, a woman who Buck left behind when he was propelled into the 25th Century. He follows her, finds out her name is Leila Markeson, and soon discovers that she was made to look like Jennifer in order to lure Buck into a trap set by an alien who wants Buck to stop a space freighter from delivering weapons to a planet his people hope to conquer. Buck gets Wilma to detonate a warhead to deceive the aliens into thinking the shipment is destroyed. Buck defeats the enemy, but loses Leila, and his lost love again, as she tearfully dies in his arms.

Twiki is kidnapped by the evil ruler of a mining colony who, faced with an uprising of the mine workers, plans to make duplicates of the mechanoid to work the mines. While in the mines attempting to rescue Twiki, Buck discovers something that will help Earth destroy a 10-ton ice asteroid that is on a collision course with Earth.

To discover the secret behind a terrifying riddle presented to him, Buck subjects himself to a mind probe in an attempt to find out who is responsible for the mysterious objects being transported into the Defense Directorate's building.

No one believes that the Vorvon, who sneaks up on his victims and drains their living soul, is responsible for a series of deaths on Space Station Theta except Wilma -- his next intended victim.

Princess Ardala returns to try to make Buck, who she considers the most genetically perfect male in the galaxy, her husband. With a powerful weapon poised in Earth orbit, she commands Earth's leaders to turn Buck Rogers over to her or else...

Kidnapped to the planet Zantia, Buck finds himself auctioned off to Ariela, the daughter of the planet's Prime Minister. Through her, Buck learns that the planet's male population are being held as prisoners of war of a people called the Ruathans. Buck agrees to help the women free their men in return for his own freedom.

Some time before Buck Roger's arrival, Col. Wilma Deering had set out to capture two interstellar gun runners. A fire in their spacecraft left them disfigured and they now set out to take their revenge on Wilma and Earth. Capturing a freighter with 20th Century chemical weapons, they plan to poison the planet's atmosphere. With the aid of retired members of the Earth Defense Directorate's 69th Squadron, Buck and Wilma attack the gun runners' base to destroy them and the chemical weapons.

After a Defense Directorate agent kills a member of a group of interstellar assassins, they plot to take their revenge on the city of New Chicago. Buck masquerades as an assassin and joins the group, but is soon uncovered. He must now, not only escape from the assassins, but also stop them from detonating New Chicago's matter/antimatter energy plant.

Most of Earth's defense squadron becomes incapacitated after ingesting poisoned food discs. Buck travels to the planet of the food's origin, Vistula, with Wilma and flight instructor Duke Danton (Groh), an old boyfriend of Wilma's. On the planet, they trace the plot to a man named Kaleel (Palance) who has been selling slaves to the planet's governor (McDowall) and secretly building an attack fleet. With so few fighter pilots, Earth's defense force is now outnumbered 10-to-1. Buck must rescue Wilma from Kaleel's mountain fortress and destroy the fleet before they can reach Earth.

In the year 1987, NASA launched space probe Ranger III, with astronaut William ""Buck" Rogers, on a 5-month trip around the solar system. However, the craft runs into a meteor storm, which disrupts its life support system and sends it into a long elliptical orbit of the Earth. In the year 2491, Ranger III again approaches the Earth, and is intercepted by the alien flagship Draconia, which is on a peace mission to Earth. Aboard the Draconia, Buck is revived by Princess Ardala and her second-in- command, Kane, whose true plan is to attack and conquer Earth. Buck is sent to Earth with a hidden homing device, which is soon discovered by Earth's Defense Directorate. After Buck convinces the humans of his true identity -- a man from the past -- he helps them to repel the Draconians' attack, with the aid of the mechanoids Dr. Theopolis and Twiki.
