Okay... so there apparently are no Super Heroes of Color.
I guess they're too busy fighting against racists and racist stereotypes.
Well, at least the Silver Surfer was kind of Black (Lawrence Fishburn voiced).
The thing is... these people don't really know each other.
Each has overcome his own demons.
Wonder Woman is chillin' with a bunch of other tall women on her home island'
Batman has a nice mansion but chills in his Batcave,
Superman has his fortress of solitude,
and who knows where The Flash lives? (The fastest man on earth couldn't be a brotha'?)
The point being - all live their personal and separate lives.
They only come together when something big happens - like the filming of a movie or animated series.
Or by happenstance - like the Surfer being stuck on Earth.
This many high powered egos couldn't function in one locale.
All are great.
All are "The Man" in their world.
But all need to be separate for their abilities to function at their peak efficiency - otherwise, they would cancel each other out.
Think about it the same way as Christ did when he sent his disciples to different parts of the known world.
If all would have stayed in the same city, nothing could have grown.
Think of the Illuminati, Bilderberg Group, IMF, major corporations or any ultra-powerful group seeking only to retain their power.
This type of power corrupts.
Even if well intentioned, this type of power becomes oppressive.
This is the message behind the Tower of Babel tales.
