Any one of the six beings forged out of space, time, light, darkness, life, energy, and matter at the start of every universe. They usually serve as mercenaries, assassins for hire, or bounty hunters. The six members are Z, D, P, S, N, and J. Though not humans, they do appear as such. Their godlike powers are virtually unrivaled in all the dimensions. They're pretty damn badass.
Me: Am I the only one that thinks the Dimension Masters are gay? ...No?
My friend: Shut the fuck up, man. They're more badass than the Avengers!
Other friend: They could totally kick Satan's ass any day!
