Zull

Zull is a planet from the Generation 1 continuity family.

There is no Dana, there is only Zull

The planet Zull is considered to be "one vast, impregnable fortress". It is led by Karzai Lorcha, who doesn't mind using the planet's defenses to protect wanted criminals in exchange for their services. Zull's inhabitants are large, nasty-looking humanoids with leathery skin, tusks and lots of teeth.

Fiction

IDW comics continuity

The Decepticon Swindle once made a deal with Karzai Lorcha, allowing him to hide from Ultra Magnus on Zull. However, Magnus tracked him down and easily broke through the planet's defenses, took out Lorcha and his guards and captured Swindle. Before leaving the planet, Magnus warned Lorcha that if he ever safeguarded any other Cybertronian criminals, he would "bring the walls of Zull tumbling down". Spotlight: Ultra Magnus
