Malastarian fuel/Legends

"Our fuel is deadly to the beast. It killed them in the past. It will kill this one now."

- Doge Nakha Urus

Malastarian fuel was a type of fuel mined out of the core of the planet Malastare. When the native Dugs began to harvest the fuel, its toxic properties drove Malastare's Zillo Beasts to near-extinction.

Behind the scenes
Malastarian fuel first appeared in "The Zillo Beast," the eighteenth episode of the Star Wars: The Clone Wars television series' second season. However, it was not identified as such until the publication of the episode's accompanying guide.
