Future Androids 17 and 18 → Future Tien Shinhan
Future Trunks reports that Tien died fighting the androids. The report does not establish whether Android 17 or Android 18 delivered the individual lethal attack. They are initially described as Androids 19 and 20, but the future opponents are later confirmed to be Androids 17 and 18.
