The Grey Corgus is a bizarre and thankfully rare creature. It is a humanoid creature that stands only 5' tall, has grey rubbery skin, 4 long and thin arms ending in two fingered hands, and two very short (2' long) legs. It's face, oddly enough is similar to the Uteni, Naruni traders, but with slightly smaller eyes that are more sunk into the face. No mouth, nose, or ears are visible on the Corgus at all, mostly because this bizarre creature has no need to breath, or eat.
It is unknown where these odd creatures came from, but it is theorized that they could be the result of some attempt at early Bio-Wizardry gone wrong, or perhaps even a mages experiment that gained a life of it's own. In any event, what few people have ever seen or learned about a Corgus, they know that it is nothing but trouble, and should be best avoided. Wherever they came from, they are tremendously ancient, with no solid clues as to where they may come from.
They seem to exist only to soak up energy in all it's forms, and for as long as the elder races can remember, there were occasional tales of great peril that were taken to try to lure a Corgus through a portal, or into some kind of trap to keep them from hurting anyone else. The forms of energy the Corgus will ingest are; Solar, Electric/Nuclear, Life, and P.P.E. in exactly that order, their favorite being Solar energy, P.P.E. being their last choice.
These creatures reproduce in strange ways. After absorbing at least 2,000 years worth of sunlight or 5 million MDC worth of energy, they will stop, their stomachs will split open, and out will pop a miniature Corgus. It will only take about 12 hours for the small Corgus to grow to full size, and will be an adult Corgus. Despite being able to reproduce, it is not believed that there are more than maybe a few hundred in the entire megaverse.
They are of extremely low intelligence, having only enough brain tissue to allow them to seek energy sources. They are so dense as a matter of fact, that whenever the sun goes down, they will begin to shuffle in the direction in which the last energy they absorbed came from. When the sun comes up, they simply shuffle into an unshaded area, and will stand there, until the sun goes down...at which time they will shuffle towards the setting sun, until once again the sun comes up in the oposite direction! Although they are not true predators, this insatiable hunger for energy sometimes makes them appear to be. Any living creature that comes in contact with the Corgus will cause it to stop, and hold on with it's two fingered hands for several moments. During this time, the Corgus will first drain the victim of all H.P. and P.E., then at the moment of death will soak up it's P.P.E.! Thus the path of the Corgus can be a disaster scene, with everything from Trees and Squirels, to Monsters and Children being found dead with no appearant wounds.
Although it may sound easy to simply stay out of their way, sometimes it isn't...especially if your' home is in the way. Corgus are not smart enough to go around, and thus will pound their way through your' home, brick walls, and even a car if it is in it's way! It is when people attempt to defend their property that trouble can come about. Firing energy weapons at the Corgus will have absolutely no effect, except it will turn from where it was heading and go towards where the weapon is. Once it sees the weapon is the thing projecting the energy that 'tastes' so good, it will stop at nothing to get that weapon, and try to soak all it's energy up. If missiles or rail guns, or any other type of mega-damage kinetic attacks are used...that can spell only disaster. The Corgus does not take well to pain, and as soon as it feels it, it will hastily counter attack, by turning in the direction from which the painful object came from, will spread it's arms out to it's sides, and will fire a HUGE energy bolt in that direction. Few creatures or things on Earth can stand up to that energy blast. With the Corgus's near invincibility, it is almost best to just let the creature pass by, and hope that it steps through a RIFT heading off of the Earth someday.
There is a secret to killing the Corgus however, and with this method comes a bonus, a weapon of un-precedented power. Unfortunately only a select few people ever have found out about this weakness, and only a handful of people in the megaverse currently possesses this knowledge however. A bounty hunter/gunslinger by the name of Madigan Morgan is the only person on Earth that knows the secret. A Cosmo-Knight on Phase World named Thratan Kethral learned the secret quite by accident when he destroyed a Corgus which came through a portal, but he doesn't know the secret about how to create the weapon. Thoth of the Egyptian Pantheon of Light has studied the Corgus, and knows the secret. He will reveal this knowledge only if the seeker is looking to do a job for him of some sort. (Has to be reasonable, as he won't just hand this knowledge away.) A Demon Slayer named Kain Zelsonaka from Wormwood travels across the Megaverse seeking out and destroying the Corgus wherever he finds them, and prides himself in being a destroyer of these beasts. He is the ONLY true Corgus Slayer anywhere. He has a half dozen light weapons, which he carries with him at all times. He has killed over 20 of the beasts, a feat unparralleled by anyone in the Megaverse. He will NEVER reveal the secret to killing them however, as he wants to be the only 'slayer' in the Megaverse.
