Going Commando box-1--1-

After defeating Ultimate Supreme Executive Chairman Drek, Ratchet and Clank became galactic celebrities. However, things started cooling down after a while. Nearly a year after their previous escapade they appeared in an interview for Behind the Hero, and were teleported to the Bogon Galaxy by the founder and CEO of Megacorp (a company that made everything from household appliances to heavy weaponry), a man by the name of Abercrombie Fizzwidget (who had a tendency to use malapropisms and often made-up words). It appeared that a masked "dupliferous criminal mastermind" had stolen a valuable experiment: a cute blue fuzzball.

Clank was reluctant to partake in another adventure, so Ratchet went solo while infiltrating the thief's airship. The Thief then hired Thugs-4-Less (their motto was "If it ain't broke, we'll break it") for protection. The dastardly thief also kidnapped Clank while he was in his apartment on Megapolis. After Ratchet came to Clank's rescue, Clank had no choice but to go along with Ratchet.

Ratchet confronted the thief on planet Siberius, defeating the thief, reclaiming the experiment, and returned it to Mr. Fizzwidget. After, Mr. Fizzwidget accidentally ejected the duo from his ship and the thief approached demanding the experiment, but had not realised that Ratchet did not have it. When the thief fell off of her ship, her mask came off, which revealed that she was Angela Cross. Angela warned Ratchet that the experiment would ultimately doom the galaxy.

On planet Dobbo, Ratchet and Clank discovered that Angela's claims were true, and tried to persuade Fizzwidget to destroy the experiment, but their efforts were in vain. The duo then stumbled across an ad for the "Protopet" (the experiment), which was being prepared for mass release. At that point, it was revealed that Thugs-4-Less terminated their contract with Angela and had been hired by Megacorp to "protect" Mr. Fizzwidget.

On planet Boldan, Ratchet and Clank were captured for "attempting to bump off" Mr. Fizzwidget. They were sent to a prison on planet Aranos. After being freed by one of Clank's admirers (a female Infobot), they headed to Thugs-4-Less HQ to free Angela, who was also captured by the thugs. The duo vanquished the thug leader and freed Angela. Eventually, the three of them went to Megacorp HQ in order to put a end to the Protopet menace once and for all.

After they went there, the female Infobot revealed that Captain Qwark (the disgraced superhero from Ratchet & Clank) created the Protopets to restore his reputation. Fizzwidget appeared and destroyed Clank's admirer, and in a surprising plot twist, Fizzwidget was actually Qwark in disguise. Then Angela then says, "Alright, what the... *beep* is going on!?". He took Angela's Helix-O-Morph (a gadget that would repair the fatal flaw in the Protopet) and zapped the original Protopet. However the action misfired and the original Protopet mutated into a gigantic monster. When Ratchet finally defeated the Protopet mutation, Clank discovered that the batteries were in backwards in the Helix-o-Morph. Angela corrected this also by amplifying the device with Megacorp's TV transponders and zapped the original, ending the threat once and for all. The real Fizzwidget then appeared. It turned out he had been tied up in a closet this whole time, and he spoke perfect English as well, with no malapropisms or made-up words.

Everyone else lived happily, except Qwark. He got a job in the Megacorp Testing Facility, acting as a test dummy for gadgets like the Crotchitizer, which he ended up taking a liking to as referred to in Up Your Arsenal.
