Essentially, the idea for it is that the Endbringers aren't city destroyers that pop up every three months, nor are they, in any reasonable manner, something you can fight. They are living apocalypses, things that destroy whole states, countries even, and the aftermaths are far starker. Death tolls are uncountable, and whole entire cultures eradicated when they show, though it bears mentioning that it's only once a year.

However, that isn't the most interesting part of them. Their mere existence changes the world, drastically. The Behemoth's movements reshape the tectonic plates, crack mountains, create valleys and leave gaping tunnels through the earth that insane people explore. The Leviathan's movements cause the weather to be utterly unpredictable, storms and tidal waves, calm tides and rainfall, are all messed up, and since he sinks whole countries (Japan is gone, under the waves in totality), the remnants are used for exploration, or floating cities are erected on the wrecks. The Simurgh's wings blot out the sun where she passes, darkening whole swaths of land, her tinkertech is left on purpose to incite greedy capes and explorers to take it, entire cities repurposed into machines that are doing incalculable things for our understanding of the world.

Human culture shifts to utter desperation instead of the slow decline of canon, as there is no rebuilding this, just a quick countdown of utter destruction that is turning the world into a completely different place then what was before. Tinkertech is more readily available, and people are far more prone to risk taking, because, well, it's not like it matters. Cauldron and other capes are wildly more active, trying desperately to just survive. Villains are seen both in a harsher light, because everyone is already fucked, could you please stop- but also in a more comprehensive way - desperation, hopelessness does that - while heroes are far more focused on making things better, on trying to help, on making the world better through the chaos, even if there are the same exact failings as before.
