No normal villain comes close to the Endbringers in terms of global impact, though there are a other well known ones:

- The Slaughterhouse Nine, a roving band of generally sadistic monsters with no goals other than terror and mayhem, having proved a threat to even the most powerful of heroes. 

- Nilbog, a bio-manipulator who's self-replicating monsters are quarantined along with him in the former town of Ellisburg, New York.

- Sleeper.

- The Three Blasphemies, Tinker constructs which interfere in European politics with unclear aims.

- The Siberian, a member of the Slaughterhouse Nine who disproved Alexandria's invincibility when she took Alexandria's eye. In that same encounter she killed Hero, the original fourth member of the team team now known as the Triumvirate.

- Glaistig Uaine, a power stealer who massacred the first groups set to capture her, stealing their powers. Hero groups successful coordinated a massive fifty cape attack on her that ended in their defeat, retreating after she claimed over a dozen of their powers and lives. The heroes responded by treating her as they would an Endbringer, calling in everyone - domestic and international, hero and villain - only for her to surrender. She is currently imprisoned in the Baumann Parahuman Containment Center, colloquially known as the Birdcage, from which escape and release are both of unheard of.

- The Ashbeast, a roving monster of fire and destruction located in Central Africa, his impact tempered only by the fact that he generally moves slowly enough to allow evacuation of cities before he approaches.

... Who exactly deposed this dictator? The Protectorate? His local superheroes? His own men?

Scion is the dumbest Idealist he has ever heard of.

... Also, his general opinion of the superheroes of this world is generally very low. They're quite good at building prisons, it is genuinely very impressive to build a prison that even supervillains cannot escape from, but if you have a roving band of nine superhumans and you haven't wiped them out what are you even doing? That's enough that they need a van, for transport, if they can't just teleport themselves across the planet or hide in a pocket dimension. The Tyrant has considerable experience trying to maneuver a van's worth of infamous criminals to evade the attention of the superheroes of the world while carrying out plans much more complicated than random mayhem, and he strongly suspects that if the heroes of the world aren't idiots due to Endbringers eating all their best rising stars the Nine have a very powerful (if dumb) Thinker or precognitive backing them. 

... Who exactly deposed this dictator? The Protectorate? His local superheroes? His own men?

So the Protectorate does not simply depose governments they disapprove of, or at least not publicly.

Well, he'll have more research to do later, but he's going to need to make some money at some point, so he can get himself an apartment and a fake ID and a computer of his own.

So. Gambling. Is it legal? Do they have procedures to detect Thinkers? Do they procedures to detect people who resemble Thinkers but technically aren't because they're Survivors not Parahumans?

Gambling's legality is varies across the US, there are government thinkers who specialize in financial crimes in the government agency Watchdog, as well as some who work directly for casinos. They aren't very public about what their methods are, but to a decent extent this is because thinkers who prevent and commit financial crimes vary wildly in powers. The impression he gets from articles about Watchdog's successes is that they only even consider investigating when at least a few million dollars appear to be involved.

Online poker also exists, often with capped earnings of any individual player to minimize the damage from cheating, superpowered or otherwise.

At the point where you have thinkers working for a government board trying to stop people from making very large amounts of money instead of conquering their own countries or at least making very large amounts of money themselves, something has gone horribly wrong. (Anyone who can hack an online poker website and cheats to observe secret information instead of draining the assets of every other player into a Cayman bank account deserves what happens to them.)

... How many of the hundred largest corporations in the US are thinker-run?

There are no obvious cases of a top hundred company being run by a thinker.

The Elite, America's largest villainous organization (which depending on the branch might not be that villainous) publicly admits control over several corporations, one of which is in the top hundred, though it appears to be tinker and not thinker run. A few others are rumoured to be run by members of the Elite but there's nothing solid.

There are three companies that used to be in the top hundred that were revealed to be secretly controlled by a villain named Teacher who could grant thinker and tinker powers. Teacher is now in the Birdcage for, among other things, assassinating the US Vice President and the British Prime Minister.

This is fantastically disturbing. It is - really not plausible that there would be so few people who want money. Maybe this is just because smart Thinkers don't tell anyone (how hard are powers to detect?) but at least as likely...

... What fraction of people with powers become capes, white hat or black?

Powers are extremely difficult to detect - there's an extra piece brain anatomy present in parahumans called the Corona Pollentia, but it's hard to verify if it's present and significant portions of the population without powers have the same thing.

Somewhere between 80 and 95% of people become capes, depending on the specifics of your definition and what study you are looking at.

That's not possible.

Counting white hats, black hats, people who engage in renumerated violence, and people who buy superpowers specifically so they can be one of the above, the figure in his universe is under ten percent. (Unless you count Livia's Legion, who distort all the statistics and so are usually left out.) Even with the fact that triggers come from stress and most supers are Survivors and Survivors need to be physically endangered to get their powers, which means that quite a lot of supervillains started by accidentally murdering someone and then descending into a spree of other crimes since all hope for a legitimate career is already lost to them. Even with the Six on the one hand and him on the other trying to persuade everyone they can to put a mask on and cause chaos. Even with federal policy designed to make life easier for superheroes and supervillains in a thousand ways closed to normal citizens. Putting on a mask and punching other masked people in the face is just not a very good way of achieving most goals! Is this universe using precognition to only give people powers in ways that would make entertaining movies to watch, or is this hostile mind control?

People really don't like discussing where they got their powers! Though this one cape does seem to be located in a place that got hit by an Endbringer, this other cape seems likely to have triggered at a place and age where she might have been a child soldier, and this third cape, a villainous child biotinker, seems likely to have been found by the Slaughterhouse Nine before she got powers.

All this seems to match 'superhero origins similar to his world's', meaning there's still an unexpected order-of-magnitude difference variable to explain and he should non-confidently model all parahumans as subject to inhuman personality modifications and therefore potentially dangerous in unexpected ways.

Still, it paints a grim picture. This world - in the sense of civilization - is ending. Not merely in the sense that his was, where democracy, more the work of Sam Colt than of George Washington, was fading as power shifted from the masses and those who could control them to the new breed of supermen, but in the sense that the new breed are not worthy of the crown, seemingly preferring to squabble amongst each other than seek rational goals. Crisis after crisis has hit until the heroes of the world are incapable of resisting the onslaught of the Endbringers, who they can't even destroy, instead hoping to drive them off so that they will destroy somewhere else?

(His heroes haven't destroyed Voidwrath. Though they have destroyed the Necromancer, or functionally so. Still a sign of greater competence.)

He can't conquer the world without saving it. And he can't save it without...

... Well. A great deal of trouble.

Actually, wait, he should do one thing before he gets to implementing his plans.

Are other worlds known? Do travelers from his universe show up regularly?

Other universes were discovered a while back by a villainous tinker, but there is only one which he can find information about - Earth Aleph (as opposed to this Earth, Earth Bet) which resembles this Earth if it hadn't gotten superheroes. A single tiny pinhole wormhole connects the two Earths.

The Tyrant probably did not look noticeably tense, he's very good at controlling it, but he will still relax quite a lot when he hears that. If there's an established multiverse, then someone in his world will invent a means of dimensional travel, the Queen will get her hands on it by hook or by crook, and then the Royal Court will arrive to bail him out. And whatever limitations he may have on his ability to face this world right now, with the Royal Court at his back he is well aware that he can beat Voidwrath in a fight.

Right then, back to using Google to locate things he will need in the short-term. Location of Indian casinos in Brockton Bay (or other casinos, if casinos are legal to run for anyone else), how to hire a cab in the 21st century, where to obtain 21st century cell phones, where to buy computers (computers are tiny even if you aren't a tinker), where the cheap local hotels are (hotels come with free internet?)... he'll do a little quick googling on 'online poker' while he's at it. And apparently Google does pictures, so a few quick shots of the local casinos so he knows what security looks like - 

And then he can worry about more research later, and go make some money.

The Titanium Tyrant's casino strategy is not actually all that complicated. Casino security may ask for ID; it doesn't look at them, not seriously, and he can, with the equipment on his person in a restaurant bathroom, adjust the birth and expiration dates on one of his to look less absurd.

It appears that they have poker being played, with decks that are shuffled in front of the players' eyes, as though they expect their players can't keep track of which of 52 identical objects occupies what position in the stack. The Titanium Tyrant needs to go to quite a lot of effort to not win a statistically implausible amount of money, but there are ordinary good poker players and he has a moderate mount of experience at looking like an ordinary good poker player, so once he's done enough of that that if he did more he might risk looking odd, he will drift over to the blackjack table, card count until shortly before his model of the people they have observing him says they will get suspicious, and then, having won a moderate, unsuspicious amount of them of the sort people quite often win, he will go on to another casino.

Once he's accumulated enough cash, the next step will be a hotel room. He plans to hole up in the hotel room, doing research, getting sixteen extremely suspicious credit cards that can nonetheless be paid back promptly and used to play in sixteen different video poker games with sixteen different accounts and fake names while he does the research, and quietly exploring his options. After a while he'll update from the hotel room to a short-term lease on an apartment, which is not a serious change to his strategy.

Then he's going to get slightly in touch with the local criminal underworld (under a fake name and with makeup and a wig and clothes that aren't his style and an unusual build, of course), buy a fake ID, one of the most expensive kind, where someone registered a fake birth and then carefully did all the paperwork for an imaginary and very boring person for decades, and then he can really get going with his plans.

During one particularly lucrative hand of texas hold'em, the Simurgh strikes Canberra.

Australia's capital city is quarantined, all 600,000+ denizens declared most likely homicidally insane. A third of the city's population is composed of refugees from Sydney, Australia - destroyed by Leviathan 13 years prior.

Yes. He knows.

At least he made a few grand with his pocket threes.

Unfortunately, the Tyrant's existence will be known to the world once he starts doing interesting things, and that means he needs to prepare everything before he starts anything.

Still, once he's made his money and has an ID that can stand up to the best the United States government can throw at it (complete with getting a driving license, which really does not take very long at all), it will be time to move to his next target. (Gambling can still serve as an income supplement, but not where he can be found.)

He needs a home base. He has very specific concerns, for just where this home base has to be. It needs to be somewhere with no known supervillains, or else only weak and mild and moderate supervillains who are much weaker than the local heroes and absolutely not holding back - which means a town, not a city (one in ten thousand people in this madhouse is a parahuman, good God) but ideally a town with an unemployment problem, that used to be dependent on a single large factory that only recently shut down. (Thus providing him with skilled labors.) It needs low property values but not an absolutely absurd crime rate such that people might trigger themselves failing to mug him, to be only lightly industrially regulated, to be within an hour's drive of a city worthy of the name, and ideally to be within an hour's flight by private jet of Washington D.C. but not close enough to the coast that he needs to fear all three Endbringers instead of only two. And it needs to have exactly the normal reaction of a failing town that depended on a single factory for work and doesn't have that factory any more and has a severe unemployment problem to someone who looks like he's rich-but-rich-from-a-working-background-who-likes-to-roll-up-his-sleeves-and-fix-his-own-damn-car-if-it-breaks who might want to open up a new factory there: Desperate, desperate hope.

This town an hour west of Brockton Bay fulfills all his requirements - it used to be a stop along the freight line that left Brockton Bay where warehouses were located, but the line no longer functions due to the collapse of the shipping industry. The warehouses are now used as auxiliary storage for the National Cheese and Diesel Stockpiles. The town attempted to revitalize its economy with retraining programs and a subsidized vocational school for manufacturing jobs that never materialized.

Sounds perfect.

He'll show up, then, and get started on his plan.

Stage one: Show up! Talk to people! Meet them! Talk to whoever in their government is panicking about their trade! Gently give the (true) impression that he runs a small manufacturing firm and is planning to build a new factory!

Stage two: Buy some land! Cheap land. Build a house! Is there a local construction company? If yes and they are competent, hire them! If yes and they are incompetent, engage in gentle competence-related politics that he is pretty sure will result in them becoming more competent, possibly due to a change in leadership! If no (more likely), hire a construction company from Brockton Bay that is competent! He's pretty sure that as a fellow hard-working blue-collar Guy Who Builds Shit he can find people he can works with pretty well. He has plans for the house which are very detailed and very clever and produce something with a very large workspace that is incidentally earthquake-resistant and hurricane-resistant and has an electric fence up to stop "deer" and excellent lines of sight and has what are not labeled on the plans as secret passageways but, once he finishes furnishing it, totally will be. (The registered copy of the plans can also be swapped out for something missing the secret rooms.) With the flood of immigration to the US, he expects he can get skilled labor very cheaply, by the standards of back home.

Stage three: Move into an apartment or motel room while his house is under construction, begin construction of the shell for a factory. He'll need investment do do more.

The most competent construction company in the area is Fortress Construction, a company which is best known for constructing Endbringer shelters. They have a branch office in Brockton Bay that doesn't normally build houses but responds to inquiry and informs him that if he wants something particularly fortified and can pay their exorbitant fees they would be delighted to help - here are some blueprints of residences they have built previously, a few of which are actually more cleverly designed than his own plans.

If that's out of his price range there's a more local but affordable construction company which does contracting work for Fortress and other major companies that is surprisingly competent, though they lack substantial experience building properties on their own. There's also a bland mid-range option in Brockton Bay that seems reasonably competent if neither of the other options will do.
