73. Superboy Prime vs. Superboy (Final Fight)
This cover is actually for their first fight, but I couldn’t find anything good to use for the second fight, so I went with the first cover!
So Superboy (Conner Kent) and Superboy Prime had a fight earlier in Infinite Crisis, but Superboy needed all the Titans and all the Flashes to make it out of that one alive, as he is severely out-classed by Superboy Prime’s power levels. And Superboy Prime made Conner think that he (Conner) really WASN’T worthy of being called Superboy.
Now, later in the series, Alex Luthor and Superboy Prime are working together to merge various Earths into one “perfect” Earth, and to do so, they’re using a special Tuning Fork Tower thing that is working off of energies from heroes and villains from the various Earths.
Nightwing, Conner and Wonder Girl make their way to the secret headquarters where Luthor is doing this (Superboy Prime is not there), and they try to stop them. They release the prisoners but then Superboy Prime shows up and starts handing out some serious beatings!
He mocks Nightwing by saying when Prime wiped out the Titans, he wasn’t even TRYING. Conner shows up and shouts that neither was he!
Now Conner takes on Prime and their battle is pitched but Conner still is not in the same class as Prime, so he likely is not strong enough to defeat Prime outright, but instead, he manages to hang strong long enough to force the pair to crash into the Tower, ruining Luthor’s plan to destroy the various Earths in his endeavor to find one “perfect” Earth and instead creates on merged “new” Earth (of course we later learn that there are more Earths out there).
As Superboy lies dying in the arms of his girlfriend, Wonder Girl, he tells her how Prime made him doubt that he was the “real” Superboy, but he showed him. She tells Conner about how he saved the world, and Conner replies with his dying words, “I know, Cass. Isn’t it cool?”
