Drexxon

The Drexxon were a race of large, bear like creatures, renowned across several galaxies as being terrible and fearsome savages. They were considered so dangerous that an allied army, lead by Perpetual Pete, went to war with them and sealed them insided a Perpetuity Chamber. (NSA: Death Riders)

Biology
An adult Drexxon was roughly five metres tall, with matted and oily thick brown fur. They also had blood-red eyes, huge teeth and large, retractable claws. They worked in packs, although would take on matters individualy. (NSA: Death Riders.)

Children Drexxon were much smaller, roughly three feet tall, which implies that they grow very quickly. (NSA: Death Riders.)

Although apperantly mindless savages, Drexxon's were capable of high intelligence. An example of this was when an infant Drexxon attempted to sabotage the Galactic Fair on Stanalan, even utilising a Neuronic Control System to control Garvo. This attempted was foiled by the Eleventh Doctor. (NSA: Death Riders.)


 * It is possible that Children Drexxon are more intelligent than the adult of the species. This intelligence may dissipate as the individual matures.

History
"Nearly a thousand years ago," an army, lead by Perpetual Pete, went to war against The Drexxons as they had destroyed "hundreds of planets" (NSA: Death Riders.) These allies managed to defeat The Drexxon and seal them inside a Perpetuity Chamber on the asteroid Stanalan, which could only be opened by the correct musical notes.


 * Although Perpetual Pete stated that these events took place "Nearly a thousand years ago," he said this at an unknown point in the future, so the time of this war is unknown.

At least two Drexxon managed to escape being trapped inside the chamber. They kept breeding for this thousand years until one infant Drexxon put a plan into motion to release its bretheren from the heart of Stanalan. (NSA: Death Riders.)

This Drexxon managed to find and brainwash the musicaly gifted Garvo. With him they managed to become and act on the Galactic Fair; "Garvo and his Marvellous Dancing Drexxon." They waited patiently until the fair came to Stanalan.

Once they reached Stanalan, Garvo and The Drexxon sabotaged the "Death Ride" attraction of the fair and caused to crash into the side of the Perpetiuty Chamber and used Garvo's musical talent to open the Chamber. (NSA: Death Riders) The Eleventh Doctor managed to foil this plot by using the local orchestra to re-seal the Perpetuity Chamber.
