- "Using highly sophisticated technology, which you couldn't possibly understand, we will be extracting a large portion of your planet and adding it to our new one. Unfortunately, this change in mass will cause your planet to spin out of control and drift into the sun where it will explode in a flaming ball of gas, but, of course, sacrifices must be made."
- ―Drek, aboard his flagship, calmly informing the citizens of Novalis of his plan[src]
Chairman Drek, also referred to as Executive Chairman Drek, Supreme Executive Chairman Drek, and Ultimate Supreme Executive Chairman Drek respectively, was a Blarg native to planet Orxon and leader of the Blarg race. He was the main villain in Ratchet & Clank, where he hatched a plan to make large sums of money. He hid this intent under the pretense that he was responding to the pollution of his own homeworld, which he had purposefully caused himself in order to commission the construction of a new planet in return for huge payoffs. Ratchet and Clank, on their first adventure together, set out to save the Solana Galaxy from the chairman's master plan. Drek was killed after being defeated in the final battle, caught in the explosion of his synthetic Blarg planet.
As a Blarg from Orxon, Drek's success as a chairman and businessman quickly led him to the status of leader of his race. However, driven by greed, he launched a scheme that first involved anonymously polluting his own homeworld. When it was rendered inhospitable to life, Drek proceeded to invade the other planets of the Solana Galaxy to extract their choicest planetary components, which he would then use to assemble a new planet for the Blarg. This way, Drek would coin tremendous amounts of cash when his own species filled his pockets with bolts by paying to inhabit the new planet. On Veldin, he revealed to Ratchet and Clank that he planned to start the process all over again to make more bolts.
While it could have already been deduced from the earliest stages of Ratchet & Clank that Drek had an immense army of Blarg Troopers and such at his side, led by the Robot Lieutenant, it was only until Ratchet and Clank reached the end of Captain Qwark's gauntlet on planet Umbris that they realized that Drek had rallied the so-called superhero at his side. On this planet, Qwark revealed his alliance with the Chairman, explaining that the latter had promised him the role of "official spokesperson" for the new Blargian planet - a promise that, beyond Qwark's realization, could never be kept. However, Captain Qwark's worth in Drek's eye lessened when the former's Blargian Snagglebeast was not able to defeat Ratchet and Clank. Nevertheless, the Chairman offered Qwark another chance to be his spokesman, but warned him to give better results. He ordered Qwark to intercept and shoot down the duo at the Gemlik Moonbase by using his personal starfighter, claiming that the Captain was "too washed up for ground combat" and placing more trust in his aerial combat skills. If he failed, Drek would cancel their endorsement deal, which painted Qwark as the superhero he wasn't. However, with the Pilot's Helmet that he had found on planet Gaspar, the Lombax and his sidekick took control of a nearby Blarg ship and shot down Captain Qwark, who crashed on the surface of planet Oltanis, marking the end of his allegiance to Drek.
Once Drek's new planet was completed, he declared that the final step necessitated before commencing its inhabitation was to place it in the ideal orbit. At the Bomb Factory at planet Hoven, he organized the construction of the PlanetBuster Maximus, which had for purpose to obliterate the planet that already occupied that ideal orbit. Unfortunately for the Chairman, Ratchet and Clank once again managed to stifle his efforts by destroying the PlanetBuster while it was leaving the planet. Despite this, Drek then led the creation of the Deplanetizer and announced through HoloVision that it would be used to destroy planet Veldin, which was the planet that currently occupied the chosen orbit for his new Blargian planet.
After learning this from Clank's mom on Planet Quartu, Ratchet and Clank rushed to Drek's Fleet to obtain the coordinates of the whereabouts of the Deplanetizer on Veldin. Ultimately, discovering Drek was on Veldin with the Deplanetizer, they met up with Drek, who had donned a giant mech-suit, and began battling him at the Kyzil Plateau. Drek was defeated on the Deplanetizer's platform, propelling him across space and crashing into his own constructed planet, killing Drek in his mech due to the planet's impact. The superweapon, at which point flipped, was then used to destroy his planet.
The Blarg, having lost their chairman and artificial homeworld, were assumingly either forced to stay on their original homeworld, planet Orxon, or move to different planets. It is unknown what exactly became of the Blarg after the destruction of their artificial planet. Either way, Ratchet and Clank had ended the reign of the Blarg and saved the Solana Galaxy. In Deadlocked, Orxon was re-visited, and it was still polluted, but not to the extent of the original game. The game mentions factory workers, so the Blarg probably still inhabit the planet.
Drek was noted for being very short, even smaller than Ratchet. He was never seen without his smart suit and tie, and his hair was always tied into an elegant topknot. He had a more pale complexion than most other Blarg and light blue eyes that glowed faintly.. It may have also been said that he harbored a certain sadistic sense of humor. Drek was both very smart and very confident, but did not take the failures of his subordinates well.
- An unlockable paint job for the Star Explorer in both Going Commando and Up Your Arsenal was called "Drek's Black Heart." As the name suggests, it was primarily black, with red streaks.
- Drek briefly appeared in Captain Qwark's flashback scene in Up Your Arsenal, when Qwark remembered his adventures from the previous two games. He was later referenced to in the same game, when Ratchet pointed out Qwark's tendency to work with the enemy.
- Drek also appeared as a floating image in the Dreamtime level of Size Matters.
- According to the manual of the first game, Drek was a "fast talking, quick-thinking dictator; a scheming' shadowy despot and a downright contemptible doer of evil." However, he never forgot his mother's birthday.
- Scenes of Drek from the first game could be seen on the IRIS Supercomputer in Tools of Destruction.
- Although never stated in-game, it's very likely that Drek chose Veldin as the Deplanetizer's target merely as a bait to lure Ratchet and Clank into his clutches in order to get rid of them, as well as destroy Veldin for an orbit.
- Drek's mech appeared as a large enemy in the PlayStation Home firing range space (past), though it did not appear that Drek was piloting it.
- Drek was quite small for his kind as his scientists and troopers (who were also Blarg) were taller.
