Chronoporter

The Chronalporter is a time travel device, located in Ben 10,000's headquarters.

Dr. Animo broke into the headquarters in The End of an Era and hijacked the Chronalporter, intending to use it to go back in time and retrieve the A.R.C. Project. Despite the best efforts of Ben and his wife, Animo successfully traveled back in time, but was returned to the present moments later by Spanner after his plan was foiled by past Ben.
