A couple of issues earlier, a Kryptonian convict escaped the Phantom Zone, and because he was infected with a crazy Kryptonian disease, he transformed into a werewolf.
Hold on, it gets better.
Batman & Superman put him down, but during the conflict, lovely young lady Sandy Terry was scratched by Lar-On. So guess what happens the next full moon?
You see the disease "changes [people] into what they identify with," and Sandy was kind of obsessed with unicorns.
But this is no mere were-unicorn...
Superman temporarily deals with the situation by flying her to the other side of the planet--who the hell said Superman is boring?!?
It is interesting that every time she transforms in this story, even though her torso undergoes the least transmogrification, she always ends up shirtless, with her bare bodice barely concealed by her conveniently long locks:
But even though he grew actual wings, his tunic never ripped off. What, no one in the audience want to Bruce's naked torso??
So the DC standard in 1979: Females can be topless but for hair cover (& still show enough side-boob to titillate the teens), but men ain't gonna strip.
Anyway, there is a typical nonsensical DC Science cure for the whole were-meshuggas:
SPOILER ALERT: It worked.
The point of this ramble? I hope we get some were-unicorn action on The Hawkeye Initiative. More likely, though? We've just launched a wave of were-unicorn fanfic upon the intrawebs. Beware!
