It’s almost a Fan Theory, but not quite a “Who Would Win?” It’s a question, however, in desperate need of a comic book story determined to discover the answer:

If the Punisher used Pym Particles to shrink the Juggernaut into a bullet, couldn’t he then kill anything?

That’s what user JoeAconite asked in Reddit’s Comic Book community, and it inspired the kind of weighty debate among self-respecting fans on line with those heard at Aristotle’s Lyceum, the Algonquin Roundtable, and San Diego Comic-Con.

As a service to comic book geeks, Upvoted sifted through the thread to pull out the pertinent information in order to get to the bottom of this conundrum.

What Are Pym Particles?

Did you see Ant-Man this summer? Pym Particles are what allowed Ant-Man to shrink. That’s all you need to know.

Why a Juggernaut Bullet?

For those unfamiliar with the X-Men or the Marvel comic books in general, the Juggernaut is a character whose namesake is a fairly accurate description of his powers: He’s an overwhelming, unstoppable force thanks to the mystical enchantment of the Crimson Gem of Cyttorak. Basically, once this unimaginably strong, practically invulnerable supervillain starts getting his march on, he turns into a Matthew Wilder hit single, ’cause ain’t nothin’ gonna to break his stride.

Check out Juggernaut doing his schtick in this clip from this classic 1982 episode of Spider-Man and His Amazing Friend (it’s in Portuguese, but you’ll get the gist):

With that kind of (un)stopping power, a Juggernaut bullet would be pretty effective ammunition. In fact, user Naedlus drops some science to prove that point.

Why Would the Punisher Want a Juggernaut Bullet?

During a picnic in Central Park, the Punisher’s family was inadvertently shot and killed by mobsters during a gangland hit. Since then, he’s filled his days advertently shooting and killing mobsters and drug dealers and terrorists and litterbugs. That’s the Punisher’s schtick, so you can imagine how useful a Juggernaut bullet would be for him.

Would a Juggernaut Bullet Actually Work?

Therein lies the crux of the debate. Some fans, while accepting the scientific impossibility behind Pym Particles, doubt a mini-Juggernaut would make a good slug because of how they interpret the nature of his powers. He’s only a truly irresistible force if he puts himself in motion.

User md_sabre1, though, had a novel way of solving that problem:

If you accept that workaround, does that make a Juggernaut bullet the perfect killing instrument? Not necessarily. You could always trick the Punisher into firing his human round into wet cement. That’s what Spider-Man would do.

Or you could just simply rely on the writer’s inability to allow a bad guy to ultimately triumph over good.
