One of the best is 'The Dark Knight Returns'. It presents an aged Batman coming out of retirement in a gritty, alternate future of the DC Multiverse. It's a story that challenges the traditional view of superheroes and their place in society.
Well, the Red Tornado's back story is really interesting. He was made by T. O. Morrow, who's a pretty devious character. At first, Red Tornado was just a mechanical construct without emotions or free will. But then, through various events and experiences, he started to evolve. He realized that he didn't have to follow Morrow's evil plans. He learned about right and wrong, and decided to use his powers for good. His powers, which include super - speed, flight, and the ability to generate tornado - like forces, are now used to protect the innocent. He's been through a lot of battles, both against his own programming and against other villains in the DC universe.
The Batman Who Laughs is extremely popular. He combines the intelligence and skills of Batman with the insanity of the Joker. His twisted nature and his dark plans make him a fascinating character in fanfiction.
One interesting concept is the twisted versions of well - known heroes. For example, a Batman who has completely given in to darkness and uses extreme and unethical methods to 'protect' Gotham. Another is the alternate versions of the Justice League where their powers are corrupted and they become more of a threat than protectors.
The Todd McFarlane's Little Red Riding Hood story is likely to be a unique take on the classic tale. It might involve his distinct art style and perhaps some darker or more edgy elements. For example, the characters could be more menacing - the wolf might be even more terrifying and the setting more foreboding.
Dark Multiverse Stories can act as cautionary tales for the main DC Universe. They show what could go wrong if certain events or character developments take a dark turn.
Well, surely Little Red Riding Hood herself is a main character. And of course, the Big Bad Wolf. There might also be other characters like her grandmother, as is common in the traditional story. But Todd McFarlane might introduce some new characters too, like a mysterious woodsman who has his own motives in this version of the story.
