-Inator Machines is a "term" invented by Dr. Heinz Doofenshmirtz, (who ended his machines' names with the term -inator), on purpose to justify his newest creations and weapons of destruction upon revealing them to Perry the Platypus, first appearing in the television series Phineas and Ferb. Over the course of the original series, all of the machines have been adapted to the term to suit with the scientist's goals. The machines also appear in the villain wars, whenever Doofenshmirtz plots his next moves.
