When Worlds Collide

Sup I'm going to pitch you my crossover fic that is When Worlds Collide. It is a massive crossover fic where the characters of Marvel and DC co-exist in one universe.

There have been other crossovers based on this concept but in my version its more than just putting characters into one universe. Its a whole alternate universe all-together and the characters play a part in how said universe gets developed.

The Idea

At the start of the series its based in a modern golden age of superheroes. The superheroes do their usual routine by fighting super villains and whatnot but there haven't been a serious threat where a group of heroes would band together since the Hydra Regime in WWII or the Skrull Invasion that interrupted and pretty much prevented a Vietnam War from happening.

So you're seeing a rise of new generation of heroes in Superman(whom is college age at this point), Spider-Man, Tony Stark, The Flash, etc. And in the first half it just showcase the world of WWC and its characters. Then build up to the big arc later.

The Tone

I want the universe to have that Timm style blend of humor and drama but without being overly immature and not too angsty either. Like what the DCAU was in the past. Especially as each character has their own distinct character trait. They're not overly brooding and not overly comical. And its those little differences that help make up the world. So the universe is idealistic but its not afraid to deliver a hard truth on occasion

I also want to build this universe with this trope in mind.

What if there is no status quo within the Marvel and DC Universe? What if characters die for good or pass their legacy to someone else? If you're expecting a kid gloves version of the Marvel/DC Universe then think again. In this universe the gloves come off and sometimes unfortunate consequences happen. Its how the heroes and other characters deal with them is what makes the universe special.

The Focus

The series will primarily focus on the current generation of heroes and how they'll establish their legacy. Which is the key theme, how does ones legacy shape the world?
