Dome of Doom

"No one escapes from the Dome of Doom."

- Prisoner to Jack

The Dome of Doom first appeared in episode XVI, Jack and the Smackback.

Background
The Dome was a savage arena where creatures from across the land were kidnapped and brought to fight against each other for the entertainment of the audience, until an opponent was either beaten into submission or if the crowd wished, killed. Jack first arrived at the Dome when he was knocked out and led across a desert along with a line of other prisoners by robot slavers. Shortly after arriving Jack found that he was trapped in a dark holding chamber and was greeted by two of the fight slaves in the adjacent chambers who explained why he was brought there. Moments later both of the creatures Jack had spoken to were elevated into the arena and ended up severely beaten in a matter of seconds, one after the other. One of them was named Poogle the Pitiful. Jack had to defeat all nine of the Dome of Doom Champions to survive and free the prisoners that were forced to fight.

It is likely that the Dome was erased from existence after Aku's past destruction, since his future tyrannical rule on Earth was undone thanks to Jack.

Voluntaries
Warriors that participated in the Dome of Doom of their own volition. Jack had to beat them all in order to free the Dome's prisoners. Below is a list of the Dome of Doom Champions:
