Little is known about Mr. Touchdown's past. According to Henry, Mr. Touchdown was a serial killer who most likely had killed several people over the course of his life.
At some point, Mr. Touchdown would meet and marry a woman and have two children, twin sons Henry and Travis. He would also start a relationship with another woman who already had a daughter named Jeane. After Jeane's mother apparently committed suicide, Mr. Touchdown would offer to take custody of Jeane as his stepdaughter, once the custody came through however, it didn't take long for his true colors to shine through as he would almost immediately begin sexually molesting her all while telling her that he loved her.
He then also began abusing his twin children as well. The abuse was so great that Henry took both Travis and Jeane, and ran away together, but they were caught by adults who altered their memories and separated the siblings, with Henry being adopted into the Cooldown family, and Travis and Jeane returned to their parents.
Mr. Touchdown and his wife would meet their deaths at the hands of Jeane sometime in the future, while Travis watches in horror.
