Dr. Animo broke into the headquarters in The End of an Era and hijacked the Chronoporter, 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 his present moments later by Spanner after his plan was foiled by young Ben in Animo Crackers.
