Superman gives Krypto to Super Boy

In 2003, Superboy moved in with Martha and Jonothan Kent in Smallville. Superman hoped that by living with the Kents, his clone would learn to be comfortable around humans and be surrounded by the most supportive people he had ever met.

When Superman figures out that Conner is struggling with living in Smallville and needs a friend, he decides to give Krypto to Conner as a gift. He does this in hopes that they will connect, bond and form a friendship similar to that of Clark and Krypto.

4 Krypto The Tracker Dog (Batman: Hush – #5)

Krytpo uses his canine skills to track down Poison Ivy

IN Batman: Shut up issue #5, Poison Ivy takes control of Superman using kryptonite-infused lipstick and sends him after Batman and Catwoman. After an intense showdown between the Dark Knight and the Man of Steel, Catwoman manages to break Superman out of Poison Ivy's mind control by throwing Lois Lane off a nearby rooftop.

With Poison Ivy in the wind, Batman and Superman aren't sure how to find her. In probably one of the most real canine acts readers have seen from the Krypt Superdog, he is given a leaf from the Poison Ivy plant in an attempt to track her down. Being the good boy that he is, he has no trouble finding Poison Ivy and later even blocks her escape attempt.

3 Taking On Mongul (Superman Volume 2 – #170)

Krypto goes up against the intergalactic warrior Mongul

While Clark Kent and Lois Lane are on a leisurely stroll in Metropolis, they are interrupted by the legendary Superman villain Mongul, accompanied by his sister (in this iteration) Mongal. Superman has his hands full and Mongul alone is enough of a challenge for the Man Of Steel. Luckily, Krypto is there to help, and before Clark can react, Krypto attacks.

While Superman deals with Mongul, Krypto takes on Mongul alone. This is probably one of Krypt's most impressive feats, using his Kryptonian abilities such as laser vision, super speed, and super strength, Krypt manages to hold off Mongul until Superman delivers the final blow. Although this comic ends with Superman chastising his furry friend for acting so rashly, readers agree that Krypto was doing what all good pets would do to protect their owner.

Many years later, when Xa-Du successfully escapes, he manages to send Superman to the Phantom Zone. While there, Superman is attacked by Krypton's imprisoned criminals, but after all this time, Krypto is still there waiting. He successfully fends off the attackers and sacrifices his chances of freedom to save his best friend once again. Superman would eventually return to the Phantom Zone to free the Krypt and reunite with his long lost friend.
