Malastarian fuel

"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 Beast to near-extinction.

Behind the scenes
"I was able to convert the Malastare fuel toxin into a poison gas."

- Doctor Sionver Boll

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