"Where No Duck Has Gone Before" is the eighth episode of the DuckTales.
One afternoon at McDuck Manor, Scrooge is awaiting a phone call from Duckburg Studios, a production company that was supposed to repay a debt to him that morning. Meanwhile, Huey, Dewey, Louie, and Doofus sit down in front of the TV to watch Courage of the Cosmos (a Star Trek type show). The character of Major Courage, a burly duck with the attitude of Captain Kirk, is practically a hero to the boys, due to all the bravery he displays on the show. Scrooge however, could care less about the show. Scrooge then gets a phone call and learns the truth about his debt. Duckburg Studios cannot repay him in cash, so instead, Scrooge has been given ownership of the studio itself. The boys are ecstatic because Duckburg Studios is the company that produces Courage of the Cosmos.
Later on, Scrooge takes the boys, Doofus, Launchpad and Gyro to Duckburg Studios to check the place out. Though the kids are excited to meet Major Courage in person, Launchpad goes on about how the guy’s stunts are just make-believe. After entering a sound stage, the group meets the actor who plays Major Courage (his real name is never given), who actually has a rather obnoxious personality when he’s not onscreen. However, he suckers up to Scrooge when he learns that Mr. McDuck is the new owner of Duckburg Studios. Scrooge announces that he’s going to cancel the show due to low ratings, unless the whole show gets a major overhaul. For starters, Scrooge orders Gyro to build a more realistic looking version of the show's spaceship set, Star Phoenix, within two weeks. "Courage" then meets Launchpad, and thinks that Scrooge is going to give the real pilot his job. When Scrooge and the others leave, "Courage" announces that Scrooge is probably going to mess everything up. He then proclaims that the show’s staff could get Scrooge on their side by spoiling his nephews (and Doofus), which is what they intend to do.
Scrooge and company return to the studio two weeks later, when Gyro’s realistic looking Star Phoenix is finally complete. "Courage" then offers to let the boys be in the episode that’s being filmed that very day. Launchpad insists on joining them as well, much to "Courage"’s dismay. Launchpad continues to argue that real pilots don’t need all the glamor that TV stars do. "Courage" starts off the episode by launching the Star Phoenix- into outer space! Gyro explains to Scrooge that he was ordered to make a more realistic looking spaceship, and that he went too far and actually built a fully working one. Scrooge goes ballistic and destroys the communications system to the ship, which prevents Gyro from telling everyone onboard that they’ve actually gone into outer space.
Launchpad is the only one on board who knows better. While "Courage" and the boys pretend to steer clear of an asteroid field, Launchpad takes control and actually avoids it. "Courage", however, takes all the credit. Launchpad then explains to everyone onboard that they really are in space, but nobody takes him seriously. Soon the Star Phoenix is taken hostage by an alien ship. Though "Courage" still thinks it's all part of the show, the boys catch on and realize that Launchpad is telling the truth. The aliens, who are from the planet Kronk, want to take over Earth, and will do so at any cost, including stripping information right out of Launchpad’s brain.
Meanwhile, the boys and "Courage" get locked up in a cell, and Launchpad soon joins them. "Courage" uses Launchpad’s “pretend to be sick” ploy to get a robot guard to come into the cell and inspect Launchpad. Launchpad places some alien food that Doofus was eating into the robot’s circuitry, causing it to blow up. He also steals the robot’s gun. After escaping from the cell, the group runs into Overlord Bulvan, the leader of the Kronks. "Courage" tries to fight Bulvan, but has no way of defeating him. Bulvan then explains that Launchpad’s gun is actually a food synthesizer, which squirts some sort of sauce. At this point, "Courage" finally realizes that the whole thing is real, and chickens out by retreating to the Star Phoenix and driving off by himself, stranding the others on the Kronks’ ship. The Kronks’ chase them through the ship, and after a slight mishap with the ship’s teleporter, Launchpad traps the Kronks in the teleporter room by shorting out the door with sauce from the food synthesizer.
Gyro finally fixes the radio and contacts "Courage" on the Star Phoenix. Scrooge then orders "Courage" to go back for the others. "Courage" refuses, stating that Scrooge can’t fire him due to his five-year contract.
Launchpad takes control of the Kronks’ ship, and heads after the Star Phoenix. After connecting the two ships, Launchpad and the boys meet up with "Courage", announcing that they’ve been saved by a real hero - Launchpad. The Kronks’ attempt to head for Earth anyway by using the information the stripped from Launchpad’s head. Luckily, since Launchpad isn’t all that intelligent, his co-ordinates sends the Kronks’ ship out of control.
Later, at Duckburg Studios, the boys are happy that Scrooge cancelled Courage of the Cosmos, as they no longer care for the show, which they pass off as “kids’ stuff”. Scrooge then explains that he had the sound stage from the show turned into a space museum so that it could continue to make money after being cancelled. As for "Major Courage", he’s stuck in an alien costume, selling candy to bratty children. "Courage" wants to quit, but Scrooge reminds him that he’s got a five-year contract.
- The episode is full of Star Trek references, from the show Courage of the Cosmos, to the title itself, which is a parody of the phrase "Where No Man Has Gone Before".
