The Pirate Robot bears a strong resemblance to a Xenomorph from the Alien franchise, a creature often referenced in Akira Toriyama's manga, such as Dr. Slump chapter 14, "Arale on the Loose: Part 1". Its appearance and general concept was also based on a robot soldier that appear in Akira Toriyama's early depiction of Dragon Ball, titled Dragon Boy.
General Blue Saga
Main article: General Blue Saga
The Pirate Robot attacks Goku, Krillin, and Bulma when they arrive in an harbor inside the Pirate Cave, looking for a Dragon Ball, as well as the pirates' treasure. It was equipped with a sword (which Krillin destroys during their battle), an arm-mounted cannon with a machine gun and flamethrower functions, a powerful tail that could electrify people trapped in its coils, and jets in its feet that allowed it to hover in the air and move quickly across ground and water.
Goku urges Krillin and Bulma to go on ahead whilst Goku vows to take the robot down and kicks it into the water which gives the two a chance to run off deeper into the base. The robot uses one it's coils to grab a hold of Goku's leg and pulls him into the water where he electrocutes him. Goku frees himself and escapes from the water, spotting a nearby large building he uses the Power Pole to ascend to the top. When the robot emerges from the water he is unable to find Goku who then jumps from the top of the building to gain increased momentum and punches through its head with a focused strike using the Rock-Paper-Scissors technique which destroys the robots power core.
The Pirate Robot was a powerful adversary up to this point in the series, taking punches from Goku and Krillin with barely any damage. Even cannon fire and being caught in a large explosion only inflicts superficial damage. A punch from the robot was enough to hurt Krillin causing Goku to comment on the robots ability to fight.

- Despite having the number 2 on each of its legs, the Pirate Robot is unlikely to be Android 2 since he was created before the Red Ribbon Androids.
- In one scene of Dragon Ball Z, during a flashback, a Prototype Android similar to the Pirate Robot can be seen hanging in Dr. Gero's Lab.
- The Cyclopian Guards from The Return of Cooler and God Guardon from Plan to Eradicate the Saiyans share a resemblance with the Pirate Robot. In addition, the Cyclopian Guards could be defeated by an opponent focusing their power into one point of attack, much like the Pirate Robot, and Goku defeats God Guardon with an attack similar to the one he used on the Pirate Robot.
- The Pirate Robot was possibly used as the basis for the Hunter Mech, a recurring enemy in the Dragon Quest game series, which, interestingly, Akira Toriyama designed most of the characters and monsters for.
- The guardians of Hell from the fourth Bleach movie Hell World, look very similar in appearance to the Pirate Robot.
- In the English dub, it is able to speak four stereotypical pirate quotes: "argh mateys", "yo ho ho", "shiver me timbers" and "walk the plank"; in the original Japanese dub, it is completely silent.
- The robot's voice had a filter on it in the original English DVD release. For the remastered sets, the filter was taken out and the voice played at its original pitch.
- Its torso armor looks eerily similar to Saiyan lower class battle armor. Given the concept of Saiyans did not exist at the time of its appearance, it may have inspired its design in the first place.
