|“||Your weapons are useless against me!||”|
|— The Prince's oft-repeated catchphrase|
|“||His power apparently lies in his choosing incompetent enemies.||”|
|— Crow (on the Prince of Space)|
A group of space men from the planet Krankor are led by their leader, Phantom, to invade Earth. But a superhero named Prince of Space (actually a bootblack in disguise) arrives to defeat the spacemen. Although the weapons of the aliens cannot harm the Prince of Space, the Phantom continues to fight, and many plot twists (including capturing a group of elderly scientists) ensue. 
- Like Shintoho's Super Giant/Starman series, this Toei production was released to theaters as a sort of mini-serial with two approximately hour-long episodes. In the US this was edited into a single feature film running less than 90 minutes.
- The main writer for the series was Masaru Igami, who worked in various tokusatsu including as the main writer for the first seven Kamen Rider series. His son is fellow tokusatsu and anime writer Toshiki Inoue.
Segment One: The bots' new game of "Sea Lion and Squirrel" is going much better. Bobo finds a suitable spot to go to the toilet, but it turns out to be a wormhole, through which The Widowmaker and an unwilling Satellite of Love enter to chase after him.
Segment Two: Due to the effects of the wormhole, each member of the SOL is moving at a different temporal speed, which makes conversation problematic, but provides ample chances for the theft of Crow's chicken puppet.
Segment Three: Due to the effects of the wormhole, Mike is replaced with a version from an alternate universe where he is also a robot. What little respect Crow and Tom have for Mike is lost as they can't take the ventriloquist dummy-styled robot seriously.
Segment Four: Due to the effects of the wormhole, Mike and the Bots are transported to a lovely sylvan glen. Tom discovers that he has hay fever. Tired of all the wackiness, Mike just goes for a walk.
Closing (Segment Five): Everything appears to be back to normal, complete with a visit from Krankor, and they're even back around the Earth, but Pearl and Brain Guy have reason to suspect they've traveled back in time to Ancient Rome...
Stinger: The Phantom of Krankor's trademark laugh.
- Due to Mike being transformed into a robot during one segment, he spends an entire segment of the movie as a robot silhouette, only returning to his normal self after the next commercial break.
- Ranked 15th in the Top 100 Episodes as chosen by backers of the Bring Back MST3K Kickstarter.
- "So is this going to be a super violent porn cartoon?"
Crow's riff plays off the fallacy that most Japanese animation (Anime) is full of scenes heavy with gratuitous sex and violence; particularly those from the late 80's and early 90's.
- "OK...two Italian guys dodge mushroooms thrown by a monkey."
- ("I'm Prince... of Space!") "Ah, hoo-hoo!"
Crow is singing in the style of the singer Prince.
- "Hey! HO-Scale Japan!"
HO scale is the most popular of model railway scales.
- "Hey look! Up there!" "It's Cheap Trick!"
- "We were supposed to meet those Heaven's Gate people here."
Heaven's Gate was a small cult of people that believed that there was a spaceship carrying Jesus following right behind the Hale Bopp Comet waiting to transport them from Earth. As Hale Bopp passed, they committed mass suicide.
- Great Hall designed by The LEGO Corporation.
Reference to a toy company that makes interchangeable brick toys.
- "The Gabe Kaplan brigade."
Kaplan is a comedian and actor known for his work as the star of the TV sitcom Welcome Back, Kotter.
- "Paging Mr. Herman."
Deep voice sounds similar to one in the movie Pee Wee's Big Adventure. When Pee Wee himself appeared in the movie based on his exploits, his voice was deepened when he said that line.
- "There goes a narwhal (Servo goes "Neee!")
- A police car's loudspeaker makes repeated announcements, Servo contributes theme music.
The music accompanies a bus' loudspeaker announcement at the beginning of "We're All Bozos on This Bus" by The Firesign Theatre.
- "Truman Capote sent to fight Krankor!"
Truman Capote was the author of In Cold Blood, Breakfast at Tiffany's, and other novels. He was heavyset, bespectacled, and somewhat effete.
- "The aliens have a Young Ones spaceship."
The Young Ones was a British sitcom about a group of students and their surreal misadventures. The remark most likely refers to Vyvyan, the punk rocker of the group, and how the fins on Krankor's ship look kind of like his spiked hairstyle.
