This is "How Can I Explain?", a feature that spotlights unexplained comic book plot points (unexplained in the comics themselves, of course, as quite often there are outside explanations, like "the artist made a mistake," etc.).

Today, we look at what the heck is Mister Sinister's obsession with Summers DNA.

As we all know by now, Mister Sinister has long been obsessed with the DNA of the Summers clan and, to a lesser extant, Jean Grey's DNA.

Honestly, so far, so good, I'm honestly not taking umbrage to that concept. He thinks that there is something to be gained by mixing their DNA together. Okay.

But look at "X-Factor" #39 (by Louise Simonson, Walter Simonson, Al Milgrom and I presume Chris Claremont was involved in there, as well), when Mister Sinister revealed that he cloned Madelyne Pryor from Jean Grey so that he could get Scott Summers to mate with her to create a powerful offspring.

But look at that plot point again. A clone made from Jean Grey was a fine enough substitute for Jean Grey in the creation of this super-being, right? So why not just clone Scott Summers and then create your own super-baby! Mister Sinister, as established in that story, had access to Scott Summers for years. He had all the access to Summers DNA that he could have ever wanted! And he didn't do anything with it!

Hell, as we have seen in "Extraordinary X-Men," Sinister literally HAS cloned Cyclops!!!

And in the "Age of Apocalypse," that universe's sinister did just what I'm talking about, just made a clone using Summers and Gray DNA, and it became the ultra-powerful Nate Grey, otherwise known as X-Man!

Sooo....well, you know, then why did he keep on obsessing over Cyclops and Jean Grey? It doesn't make any sense!
