In their quest for world domination, the pair of gene-spliced lab mice traveled through time multiple times, both in their role as an Animaniacs guest feature and in their own series. Their jaunts include a visit to H.G. Wells and his time machine.

As with the Warners in other Animaniacs episodes, it’s not always clear whether Pinky and the Brain are traveling through time or merely acting out a drama set in a different time period. Such is life within four walls.
