The Combine-O-Tron 2000 is an invention built by Melvin Sneedly. It has the ability to combine two things into one thing. The Combine-O-Tron 2000's effects can be reversed when the batteries are turned around. According to Melvin, it usually takes from a few months to at least half a year to build as building a cellular combiner is extremely difficult.

History[]

Captain Underpants and the Big Bad Battle of the Bionic Booger Boy - Part 1: The Night of the Nasty Nostril Nuggets[]

Melvin reveals the Combine-O-Tron 2000 to his class as part of Demonstration Speech Day. There, he uses it to combine his hamster, Sulu, with a small robot.

Later, Melvin grabs his Combine-O-Tron 2000 and heads home. After a few hours, Melvin has built a super-powered robot, which he plans to combine with himself. When the Laser Extractor from the Combine-O-Tron 2000 fires the lasers, Melvin sneezes at the last second, transforming him into the Bionic Booger Boy.

Near the end of the story, Gaylord Sneedly aims the Combine-O-Tron 2000, which is now reconfigured to separate objects, at his son and fires. The Bionic Booger Boy bursts into chunks of boogers and metal. Melvin and Benjamin Krupp, who was swallowed by the Bionic Booger Boy as Captain Underpants, are now free. Unfortunately, the robo-booger Trixie grabs the Combine-O-Tron 2000 and destroys it.

Later, Mr. Melvin builds a time machine to retrieve the Combine-O-Tron 2000 before it was destroyed. George and Harold trick Melvin's father into giving them the device while switching it with a fake. George then zaps Gaylord with the Forgetchamacallit 2000 as the confused Gaylord goes back to his wife, where it ends up destroyed like the original.

Once George and Harold return to the future with the machine, Mr. Melvin uses the Combine-O-Tron 2000 to return him and Captain Kruppy the Underpants Kid to their original bodies.

Later, George and Harold return to the scene of Big Melvin beating up Captain Underpants. Harold aims the Combine-O-Tron 200 at Big Melvin and Captain Underpants, transferring the former's superpowers back to the latter.
