Death to the Squishies!
Ratchet is frustrated. He's tired of robots getting all the glory while he does the hero work and receives no credit. He feels overlooked, especially with Clank getting star treatment for his role in the "Secret Agent Clank" T.V. show. Even the President of the Galaxy is acting like a star-struck fan.
Clank is a great guy, but he spends most of his time as a backpack. And the Galactic Ranger bots, supposedly guardians of universal peace, seem to have a "cowardice feature" programmed in. Ratchet is the one who experiences real pain when a Tyhrranoid attacks, so he feels he deserves more respect.
Nefarious Rumors
On top of the robot worship, there are disturbing rumors circulating the galaxy. The word "squishy" is being used as an insult to describe living things, implying that being alive is no longer considered cool.
The news is showing scenes of Ratchet's home planet, Veldin, under attack by Tyhrranoid raiders. These raiders are rumored to be funded by Dr. Nefarious, a flesh-hating robot supremacist. He plans to obliterate all living things.
Dr. Nefarious's Plan
Dr. Nefarious has convinced a gullible warrior race, the Tyhrranoids, to become his allies in destroying all organic life. The Tyhrranoids, lacking a concept of irony, don't realize that Nefarious plans to annihilate them once they've completed his dirty work.
Currently, a huge Tyhrranoid attack squadron is looting the streets of Veldin. Ratchet and Clank must assemble the deadliest arsenal of weapons the galaxy has ever known to defeat the arch-supervillain Dr. Nefarious. The Mission Ahead
Ratchet and Clank must stop this robo-felon. The good news is that a crack team of space commandos will cover their backs. The bad news is these commandos will actually be protecting the meatloaf in the command ship cafeteria. No worries, though. Ratchet is in an edgy mood and ready for whatever comes next. It's time to visit Veldin and deliver some well-placed powder burns. Perhaps some intergalactic devastation will cheer him up. Ratchet has a shipload of new weapons and is eager to use them on the next smartass alien who shows too much attitude.
