Umm, in terms of far reaching world impact, Hitler qualifies at the very least as an Anti-hero.? He has been immortalized in stories and tales since.? Supernatural powers have been attributed to him.
Possibly yes. Mind you, he'd be a very weak Eirei; his fame might qualify him but he still needs to stand on his own (actual) skills, which he has none. Well, he might have an EX in Charisma.
Rasputin is another one.á Famous durability and purported mystical powers.
Another possibility.
What about Hans-Ulrich Rudelá or Erich Hartmann?á For Rudel, 2,530 combat missions claiming a total of 2,000 targets destroyed; including 800 vehicles, 519 tanks, 150 artillery pieces, a destroyer, two cruisers, one Soviet battleship (the Marat), 70 landing craft, 4 armored trains, several bridges and nine aircraft which he shot down in a Stuka.á In terms of pure killing shit, this is at least the equal of several FSN heroes.á For Hartmann, 352 confirmed aerial kills, an Ace of Aces if there ever was one.
See, this is where you begin to misunderstand what it means to be an Eirei. It's not about how many people you kill, although that helps. It's about being a legend, and a very specific kind of legend.
In the Nasuverse, the Excalibur is only a powerful NP because of King Arthur, not the other way around. Aside from Shirou (and he has a Reality Marble to hax this), anyone else who tries to use it will find it's just another typical sword, that is, if they can use it at all. But with the Nasuverse's King Arthur, Excalibur really is a beam-spamming sword with an immortality-granting sheathe.
Can you say the same about Erich Hartman? Can you say that his weapons, his guns, his planes, truly, mystically,
belong to him, in the same way that Excalibur is Arthur's? Can Erich Hartman make his planes do, not only the improbable, but the impossible? I'm not talking just being able to blow up a few hundred planes over the course of a war, I'm talking about being able to shoot beams of light, eat souls, and go mach ten kind of plane.
If Erich Hartman had a skill where he could take a plane, any plane, by himself, and it would suddenly become death incarnate despite all logical evidence saying it's impossible (like say, a propeller driven plane managing to reach mach seven in a climb when Erich, and only Erich, controls it), then this might apply. Otherwise, no.
TLDR: For a modern hero with modern weapons to apply, they need to have mystically
exceeded the logical limits of their modern weaponry and made said weaponry theirs. A man with a machine gun taking down ten thousand soldiers is nothing. A man with a machine gun taking down every alien craft in Independence Day and War of the Worlds combined
might qualify.
