I’m not going out on much of a limb when I say that one of the best parts of James Gunn’s Superman was Krypto. Everyone knows that, but plenty of people don’t realize that Krypto’s just one of the DC Universe’s many Super-Pets. Perhaps you’ve heard of some of the Kryptonian dog’s slightly less famous furry colleagues like Comet the Super-Horse or Ace the Bat-Hound. But what about Streak? No, not Streaky the Supercat—Streak the Wonder Dog. And no, he didn’t belong to Wonder Woman.

If you haven’t heard of him, don’t worry, you’re hardly alone. But there’s no reason we can’t change that. With Krypto poised to return later this year in Supergirl, we thought it might be a good time to spotlight some of DC’s more obscure animal sidekicks. These guys likely won’t be making their way to the big screen anytime soon, or well, probably ever. But that doesn’t mean they don’t hold their own…erm, underdog appeal. Here are five delightful, but largely forgotten Super-Pets. Perhaps someone in the DCU can find them and offer them a new home?
 

Streak the Wonder Dog

The year was 1948 and the Green Lantern Corps hadn’t been introduced yet. However, Alan Scott had something better than an intergalactic backup team, he had Streak the Wonder Dog. Introduced in 1948’s Green Lantern #30, Streak was Alan Scott’s dog and would occasionally join him on his crimefighting adventures. The canine companion was such a hit at the time that he eventually got top billing over Green Lantern himself and even appeared in a few solo stories without his master. Streak eventually disappeared from comics, and in JSA Classified #39, we learn that he died of old age.
 

Fuzzy the Krypto Mouse

Introduced in Superboy #65, Fuzzy was a pet mouse that belonged to a young boy named Tommy Ewell. One day Fuzzy wandered into the middle of a science experiment that gave him superpowers. Tommy was surprised to discover Fuzzy’s new abilities and to see that he had grown to the size of a human child. Still, he was willing to roll with it and gave Fuzzy his old Superboy Halloween costume, dubbing him Fuzzy the Krypto Mouse.

The problem was Fuzzy still retained the intelligence of a normal mouse, so he basically flew around Smallville doing mouse stuff, like stealing cheese and punching images of cats. Even stranger, the people of Smallville blamed Fuzzy’s actions on Superboy, because for some reason they couldn’t tell the difference between their hometown hero and a giant mouse. Fortunately, the effects of Fuzzy’s science experiment wore off after 48 hours, returning him to his normal state…but not before he crushed a piece of coal into a diamond, paying for Tommy’s college education.
 

Nighthound

There’s no easy way to say this, but Superman and Jimmy Olsen had a pet dog they kept in a bottle. Yes, a bottle.

During the Silver Age, Superman and Jimmy Olsen had this strange hobby where they would shrink themselves, go inside the bottled city of Kandor, and fight crime as a pair of Batman and Robin knockoffs called Nightwing and Flamebird. (That’s right, Superman was Nightwing years before Dick Grayson. Sorry you had to find out this way.) Anyway, as part of their weird superhero LARPing, Jimmy and Superman had a canine partner called Nighthound.

Nighthound was a psychic bloodhound who could track people from their psychic signatures, but only if they were awake. Jimmy made sure Nighthound wore a mask, so that no one would learn the secret identity of a dog that never left the bottled city. Nighthound had two appearances in Superman’s Pal Jimmy Olsen #69 and World’s Finest #143 before he was almost entirely forgotten. Hopefully someone in that bottled city is still taking him out for walks.
 

Serge the Possibly-Psychic Horse

You may have heard of Jumpa, Wonder Woman’s pet kanga, but did you know she also had a pet horse? Diana’s horse Serge was only seen twice, in 1943’s Wonder Woman #3 and Comic Cavalcade #7. The thing about Serge is that Diana suspected he had a special sixth sense for danger and that he could understand her. However, in both of Serge’s appearances, Diana quickly ditches him to do Wonder Woman things. When you have an Invisible Plane, why would you need a horse, even if he might be psychic? Maybe if she knew he was psychic for certain, it would have been different. Then again, considering she spent all of six total pages with Serge, how could she know? She should probably have spent some more time with him.

Oh, and I don’t know why I feel the need to mention this, but when I say, “spent more time,” I don’t mean in a romantic sense. It would be utterly ridiculous for a DC Universe superheroine to date their psychic horse.

*Looks uncomfortably at Supergirl*
 

The Other Krypto

In a world with multiple Robins, Green Lanterns and Flashes, it should come as no surprise that there is another Krypto. Introduced in Adventures of Superman #501, this Krypto was an Earth dog who was originally owned by Superman superfan Bibbo Bibbowski. Bibbo named the pup Krypton, but there wasn’t enough room on the dog collar, so he settled for Krypto.

Feeling that Metropolis was too dangerous for the pup, Bibbo gifted Krypto to the telepathic genomorph Dubbilex, who hoped to use the dog to teach Superboy responsibility. Superboy and Krypto DID NOT get along. (It wasn’t too different than David Corenswet’s relationship with Krypto in Superman, now that I think of it.)  This version of the doggo hasn’t been seen since 2000, as he was quickly forgotten when DC brought the original Krypto back after a long hiatus.
 

Who knows, maybe we’ll see some of these Super-Pets again. I’m sure Nighthound is patiently waiting for Jimmy and Superman to come back, Wonder Woman may have to enter a potentially dangerous horse race and with college education costing more than ever, now is the perfect time for Fuzzy to return. And if we don’t…well, at least we know Krypto will be back!
