Maulkiller was a malehybridclone created on the planet of Kamino by Darth Vader, Dark Lord of the Sith. Maulkiller was created by combining genetic material from the Dathomirian Zabrak Sith apprentice Darth Maul and the deceased Human Galen Marek. The resulting individual had goldeyes and his skin was silver with black tattoos. Disparate differences between the two samples caused physical and mental instabilities that led to the clone’s destruction not too long after its creation. Maulkiller struck fear into all who faced him, including Darth Vader himself.
Maulkiller appeared in 2010 as a GameStop exclusive bonus preorder avatar for players of the Xbox 360 and PlayStation 3 versions of the video gameStar Wars: The Force Unleashed II. The preorder bonus also came with «Maulkiller Silver SaberCrystals,» which used less Force Energy. The article The Good, the Bad, and the Gorog in Star Wars Insider 121 revealed that Maulkiller came about when team members on the project were brainstorming ideas for combat wardrobes, and that the character was inspired by Darth Maul.
