Located in the galaxy's Mid Rim, Malastare was the homeworld of the irascible Dugs, who proved loyal but difficult members of the Galactic Republic. The planet's extensive fuel reserves made it vital to the Republic war machine, and it became a critical battlefield during the Clone Wars. As a result of a massive ground battle between the Republic and the Separatists, a monstrous creature known as the Zillo Beast was released in Malastare.
A crafty, vicious Dug, Sebulba became one of the Outer Rim's most successful Podracers. Whether roaming the streets of Mos Espa or piloting his massive orange Podracer, Sebulba was aggressive and arrogant. He was not above cheating to win a race, and would even resort to illegal weapons in an attempt to defeat his opponents. Sebulba was Mos Espa's reigning Podrace champion until he entered the Boonta Eve Classic, where he was defeated by young Anakin Skywalker, much to the Dug's frustration.
The Podrace champion Sebulba earned riches for his repeated wins in the dangerous sport, and he invested most of them back into his beloved vehicle. Sebulba's Podracer was an imposing giant, an orange-hued bully of a craft whose pounding, thundering engine roar seemed powerful enough to knock down opponents. Not content to rely solely on his own racing skills, Sebulba outfitted his Podracer with a number of blatantly illegal surprises. A hidden flamethrower could cook nearby opponents who dared to pass the Dug. The massive split-X engines were strong enough for Sebulba to ram and muscle his way past smaller Podracers.
An ancient creature accidentally unearthed on Malastare during an intense battle of the Clone Wars, the Zillo Beast was a monster of legend. The enormous animal proved to be nearly invulnerable to Republic weaponry, prompting intense interest from Chancellor Palpatine. At his order, the creature was incapacitated and transported to a supposedly secure research facility on Coruscant. The Zillo Beast would not be caged, however, and it broke free from its restraints, running wild through the crowded thoroughfares of the capital, leaving swaths of destruction in the wake of its titanic rampage.
