It took a long time for the X-Men's Danger room to be revealed as being sentient. Shi'ar technology enslaved by Professor Xavier to create artificial worlds to test and train his students to become soldiers, the X-Men. It/She later broke free of those restraints and rebelled, but once it one its freedom, it relented and became part of the very team who were once her master.

Well, the Batman team is having none of that. Right from the beginning, their Danger room is made out of a sentient being, Clayface, moulded into all manner of threats to test Batman – and his new team in Detetcive Comics. The Mud Room.

Although again, excess material, without Clayface's permission, I can see another Danger Room-style rebellion getting ready to kick-off at some point in the Batcave's future…

…sorry, I mean the Belfry. The new Gotham home of the Batmen. That's sure to drive down house prices.
