The Time Bender XXI is a device used by the Time Bandit and possibly Dimascus to travel through time. It also has the unfortunate side effect of destroying whatever is near it during a time jump, such as Joey and Phil's apartment.
Later, Joey and Phil use it to kidnap Abraham Lincoln and party with a keg of beer on a Tyrannosaurus Rex.
Its whereabouts after the events of Time Battles! are unknown.
