DC's Cyborg knows the perfect way to beat Wolverine. On the face of it, Wolverine should be the most dangerous man on the planet. As a mutant, he has a phenomenal healing factor that has allowed him to survive being burned down to his bones, or cut in half by a portal. The Weapon X Project then enhanced him by bonding his bones with adamantium, an almost indestructible metal, and his claws can slice through almost anything.
Wolverine has gone up against gods and monsters, rogue mutants and powerful cosmic entities. In the popular and much-acclaimed Enemy of the State event, Wolverine was brainwashed and turned into an assassin for the Hand, and every Marvel hero in the world trembled in fear. At one point, Wolverine broke into the Baxter Building in an attempt to assassinate the Fantastic Four, and even with Reed Richards' genius the FF barely survived.
Hilariously, in today's Justice Con interview, Ray Fisher - aka the DCEU's Cyborg - revealed he knows the perfect way to stop Wolverine. As Fisher notes, he grew up with comics, but he always had a preference for DC. He joked that he was one of those 11-year-olds who consistently argued Batman could find a way to beat anybody. He tossed out a few examples to prove the point, and his idea for stopping Wolverine is simple but absolutely perfect; just get a magnet, he suggested. Just get a giant magnet. After all, adamantium is magnetic, as Magneto has demonstrated on occasion.
Amusingly, Fisher is right; get a big enough magnet, and you could conceivably keep Wolverine captive. The problem, however, is that you'd need to make the magnet big enough to have the effect, and it can actually be pretty expensive to produce a magnet of that size. Of course, cost would be no object for the billionaire Bruce Wayne, so if anybody could pull this off, it's Batman.
Another option would be to make a magnet more powerful, most likely using electrical coils to generate a stronger magnetic field. That approach has actually been tried a few times in the comics, but it has one major flaw; those coils make perfect targets for Wolverine's claws, allowing him to cut through them. His escape isn't easy and it's hardly painless, but all it ultimately accomplishes is leaving Wolverine in a very bad mood. And that's the risk with attempting to capture Wolverine; in theory the magnet idea works, but if you fail, you wind up in serious trouble.
