Earth-27750

Earth-27750 is a collaboration universe between D227 and J50A, one of the many collaborations the two have ever made. This universe however, is built to last, compared to the two's other works in the past that're abandoned mostly due to the lack of interaction between the two, as well as coordination (due to the creators' different time zones that slow them down). This universe's contents are made of fanfictions made by the two creators, with reimagined character origins (though they're not getting into origins straight on, at first). This universe is based on the MCU, DCCU, CW's Arrow TV Show, as well as Flash, and even other sources, such as books and other comics, as well as some video games.

The Day of Reckoning (Justice League)
The first major story arc in this universe, the story arc introduces the universe itself, and the condition of the universe's Earth, as well as its inhabitants, especially vigilantes and enhanced individuals. The world's been filled with heroes and villains, gods and monsters, and a lot of other supernatural things. Most of the "officials" fear that they'll take over the world themselves, but one man seeks to prove that "super-heroes" do exist, and they will protect mankind with their lives. And on the same time, a threat beyond Earth seeks to dominate Earth itself, and an unlikely team of "heroes" are about to prove themselves to the world. They are... the Justice League!

Warlords of Draenor (Justice League/Crossover)
After the League's first success in repelling the first major problem that threatens the entire world, they have continued to preserve peace in the world, with the help of other heroes, as well. But months after their times of "peace", the League discovers a bigger threat lying in another dimension after a shocking finding of a being from another world. And they soon found something bigger than they expected. A new world, in another dimension, called "Azeroth", filled with not just humans, but beings that are known to be non-existant in the world of the League, including a race that threatens the existence of Azeroth. Will the League succeed in defending Azeroth? Introducing the elements of the hit-game, World of Warcraft to Earth-27750! And while the major heroes of the Justice League are away... what will happen to Earth, without their protection?

Of Terrors and Marvels (Captain Marvel)
Carol Danvers, AKA Captain Marvel has been working with Earth's heroes for thousands of times. Saving the world with them, defeating her own gallery of villains, and others. He's also a member of SWORD, an organization formed to keep Earth safe from intergalactic threats, in case the heroes aren't available. And now, SWORD has requested Captain Marvel's assistance in a possibly planet-threatening problem of an invasive alien species called... the Xenomorphs. And it's up to her to stop them. Either she'll blast them to pieces and save Earth, or get killed by legions of black-skinned savage aliens.

The Year of the Knight (Batman)
Batman is one of the greatest herose Earth has ever known. Even without powers, the villains of Earth fear him, as the Dark Knight swoops in and deals his taste of vengeance to them. But what exactly defines him before he joins the Justice League? Taking back to the Knight's early days, we see how the Bat struggled to deal with his hometown's deadliest felons, thugs, hitmen, crime bosses, and even the earliest supervillains there are, and also see the greatest threat Batman has ever encountered in his life. And also, a brief glimpse of one of his (also) greatest enemies in the future...
