== History ==
Clockwork debuted as the deuteragonist of the series' second special The Ultimate Enemy. He is initially presents himself as an enemy of Danny, but is secretly giving him a test of character after seeing him cheat on CAT after witnessing his turn into Dan Phantom in one timeline. However, Clockwork stops the explosion that kills Danny's friends, family and teacher after Danny proves himself and declares he will never turn into the dark version of himself and gives the boy a second chance after seeing Danny is not a cheater and then becomes an ally to Team Phantom.
He later appears in "The Masters of Time", where he lets Danny go into his parents' past to stop Vlad from getting powers. However, it only creates an alternate future in which his father Jack gets the Ecto-acne and Vlad and Maddie are married. Clockwork tells Danny to save Vlad, Sam and Tucker in the present, not the past and is seen smiling, showing Clockwork was secretly testing him yet again.
