As comic book fans, we’ve all had discussions with our friends about who is the greatest superhero of all-time. Who is the strongest? Who is the fastest? Who would win in a fight? These are all popular questions that have been asked and answered time and time again. For that very reason, let’s ask a different one. Let’s try to answer the question: Who is the greatest superhero pet of all-time? 

#5 Zabu 

Zabu is the faithful sabretooth tiger companion to Ka-Zar of the Savage Land. Having saved Ka-Zar from a group of bloodthirsty savages when Ka-Zar was a boy, the two have been inseparable ever since. Zabu is the only known sabretooth tiger in existence, and is a cunning hunter with a near human-level intelligence. 

#4 Krypto the Superdog 

One of the most well-known super hero pets of all-time is Krypto the Superdog. Krypto was the loyal pet dog of Superman back on Krypton when the Man of Steel was just a toddler named Kal-El. Krypto was launched into space in the same type of rocket that Kal-El was. However, Krpto’s rocket landed on Earth much later. Eventually the two were reunited. This superdog shares the same powers as his human counterpart, making him one of the strongest pets in existence! 

#3 Ace the Bat-Hound 

Never one to be outdone by Superman, Batman also once had a loyal four-legged companion of his own in Ace the Bat-Hound. This faithful and fierce German Shepherd was found by Batman and Robin after his owner was kidnapped. The three teamed up and eventually rescued Ace’s owner, John Wilker. The man eventually became too busy to take care of Ace, so he left him to Bruce Wayne. Ever the clever one, Bruce decided Ace could be an asset to the Bat family. Because he wanted to protect his own identity as Batman, Bruce fashioned Ace with a mask of his own which sported the bat-emblem. 

#2 Throg 

The story of Throg is a sad one, as he was formerly a human named Simon Walterson. After losing his wife and child, Simon fell into a bad depression, which led him to seek out a witch to help him speak to his wife one last time from the afterlife. Though Simon’s wish was granted, the witch turned him into a frog when he couldn’t pay for her services. Years later, Simon’s fortunes changed yet again, when one day he found a tiny piece of Thor’s hammer. Throg was worthy enough to pick it up, and obtained the powers of the god of Thunder himself! 

#1 Lockjaw 

It should come as no surprise that a dog would be at number one. There is no more loyal companion than man’s best friend. What sets the Inhumans’ Lockjaw above the other canines, you may ask? It’s quite simple… Lockjaw has the ability to teleport through dimensions, has super dog strength, and can even predict the future! Plus, he’s royalty. What truly separates Lockjaw from Krypto and Ace though is his staying power. Though his original appearance doesn’t go back quite as far, Lockjaw has maintained a consistent role within the Marvel Universe since 1965!
