Twice-Told-Tales: The Krull... the Answer Man... and the Space-Beast

Evan Wright, the "Answer Man of Space", was the 22nd Centuries greatest intellect. With a photographic memory and a prolific aptitude for reading copious amounts of facts daily, both in the United Solar Worlds Building and on his evening Wright Answer telecast. However it was a young lad named Jon Drew, who heard of the mysterious Krull, continued to ask Wright about this long-gone race of aliens. Not wishing to display ignorance contrary to his famous disposition, the Answer Man gave answers based on hypothesis rather than concrete evidence. 

However, when a starship known as the Starfire had to land atop a mad-made planetoid in order to implement repairs, the centuries-old robotic sentinels informed the human crew of their assignment to vanquish a metallic Space-Beast upon its return, as it had decimated the Krull's planet repeatedly eons ago. However, at the critical moment when these astronauts landed, and the space-beast returned, the robots withered and no longer functioned! What would stop this monster from consuming the planetoid and, by extension, the crew of the Starfire?

 

Turns out, their plight had been broadcast and a young Jon Drew realized that his idol, the Answer Man, could save them. Using deductive reasoning, Wright was able to deduce that the copper arm of one robot and the zinc arm of the other were to be placed in an acidic vat adopt the planetoid, which was actually a floating weapon designed by the Krull. Since these automatons were the triggering mechanism, the humans lifted the robotic arms as instructed which destroyed the space-beast once and for all! And thus, although it was vanity that caused Wright to portray himself has having the right answer, it was his knowledge and desire to assist his fellow man which save the lives of these men. (Interestingly. this Space-Beast somewhat resembled the Flame Dragon of Krypton-One and the Snagriff of Krypton-Two that battled each Superman once. They also very much resemble the Golden Roc of Appellax and Space Dragon of Yzgartyl that battled the Justice League and Society members Green Lantern and the Spectre, respectively).

  

What is truly amazing is that this exact same event transpired on both Earths One and Two!. How do we know that this transpired exactly in each of the  universes? Well, as we had previously considered, the Krull (alternatively known as the Krell) had contact with Superman of Earth-One and Wonder Woman of Earth-Two. As indicated in World's Finest Comics #249 and Superman Family #192 (in February and  November 1978 respectively), with the former detailing the pact that Krell leader Oragon made with Nazi Germany and their agent, Doctor Psycho.  

The latter tale was what could have occurred via a Computer Probability Simulator  hypothesizing what would happen in a world without a Superman. However, the actual Superman of Earth-One later met the Krell who at this point were saved by the Man of Steel. That this same story of the Answer Man of Space was twice-told-tale is that both tales link to a footnote referencing the same story in Mystery in Space #13, where this tale was originally shown!
