Mega Cruiser

From Ben10versepedia

The big battle ship that Ben and Kevin Levin are taken to and forced to participate in gladiator-like games. It is controlled by Slix Vigma. On the Mega Cruiser, the gladiators are kept in a large room with each other. Special tubes eject a purple goop, which is their only food.

The Mega Cruiser also has Emergency Escape Pods & a Galactic Hyper-Jump feature.
