Synopsis for Supergirl: "The Day Super-Horse Became Human!"
When Comet sees Supergirl kissing Jerro and Dick Malverne on Valentine's Day, he longs to be able to romance her himself as a human. Accordingly, he travels back in time and petitions Circe to use a magic solution to turn him into a normal human without super-powers. She complies, but says that he will regret his decision. When Comet returns to 1964, his memory is affected by the serum and, before he can change to human form, he becomes involved with a thief called the Hooded Demon. Later, Comet becomes a human and regains his memory, but is mistaken for the Demon by the police. Still, Comet (as Bronco Bill) gets to kiss Linda Danvers and carries on a brief romance with her. Finally, when Supergirl's life is threatened by a Kryptonite meteor and when he is still threatened with false imprisonment, Bronco Bill asks Circe (who is watching him in the past on a crystal ball) to turn him into Comet again. She does, though the transformation is out of Supergirl's sight. Comet rescues Supergirl from the Kryptonite, and is gratified to hear her speaking romantically about Bronco Bill later on.

- This specific Red Kryptonite transformation is a callback to Action Comics #293. Normally Red K does not affect any given Kryptonian twice, but in this story Superman is using that piece to create an antidote to Red K.
- In Action Comics #312 it is said that Red Kryptonite doesn't effect a Kryptonian the same way twice.
- There seems to be a continuity error with the Phantom Zone ray projector as not only does it look different but the evil Superman is able to crush it which being from Krypton should be impossible.
