Biobliterator

The Biobliterator was Dr. Nefarious's superweapon that ravaged Metropolis on Planet Kerwan and many other planets in the Solana Galaxy, turning the inhabitants into robots. However, the Biobliterator required a massive amount of energy, and had to refuel on planet Koros. Only two were ever built and both met their demise. The first one attacked Kerwan and various other worlds before being destroyed by an Ion Cannon built to defend Biobliterator from the Galactic Government of Solana only to hijacked and used against the weapon. The second one had built on planet Mylon just recently and improved on the formers one by being larger, creating stronger robots and be able to transform into a giant mech. It was defeated by a Hovership piloted by Ratchet.

History
Ratchet and Clank first discovered the existence of the Biobliterator at Dr. Nefarious' factory on Planet Daxx by hacking into the databases. The Biobliterator's purpose remained a mystery, but it first came to light when Skid McMarx was turned into a robot by Dr. Nefarious' ally, pop star Courtney Gears. Ratchet managed to defeat her, but Skid was to remain a robot for a while. When Metropolis was attacked and its people turned into robots, the galaxy finally caught on with Nefarious' intentions. On Zeldrin, the duo found a datadisk Captain Qwark tried to obtain when Nefarious' cruiser was destroyed in Zeldrin orbit. Using the info in the datadisk, Big Al discovered the full extent of Nefarious' plan and learned that Veldin would be the next target. This brought the duo to planet Koros.

It was on Koros that Ratchet and Clank found the first Biobliterator and destroyed it with a ion cannon, unaware that Dr. Nefarious had already created a second, improved version of the Biobliterator. The second was larger and transformed into a giant robot armed with thousands of missiles that Ratchet, Clank and Captain Qwark destroyed at the Launch Site after beating Dr. Nefarious. It was the final boss of the third game. Once the head exploded, Nefarious and Lawrence were stuck on an asteroid until it crashed landed on Zanifar many years later.

Weapons and Ornaments
The Biobliterator was a large superweapon that was outfitted with many armaments. Its armor was impervious to most weapons. Its main weapon was a large beam shot from its "eye" that turned any who came in contact into robots under Nefarious' control. The second Biobliterator had the ability to transform into a massive robot armed with thousands of missiles to shoot down enemies

Boss Strategy
The Biobliterator serves as the final boss of the game. While it's not as difficult as Nefarious, it can still be a challenge to defeat. Ratchet must use the Hovership to destroy the mechanical behemoth. The Biobliterator attacks by unleashing a swarm of missiles, and firing energy blasts. If it successfully shoots down the Hovership, use the Turbo Slider to find another one.

Another alternative to this is to use the flux/splitter rifle and PDA, to snipe The Biobliterator from a distance. Over by the the hovership is a metal mass and what looks like Clank's head, this is the perfect spot to hit The Biobliterator and hide from the missiles.
