The W&WSA gang traveling through time
Waluigi and Koopa on the Time Machine
The Time Machine is a machine created by Professor E. Gadd. It has appeared in one video so far: Wario and Waluigi's Super Adventures Ep. 1-4. The Wario Bros. used it to stop Shadow from being created, but they were abandoned by the Time Machine, and had to build a new one on their own. Eventually, they left the Shadowball in the past, so the whole journey was pointless!
