Often it starts with mutual respect. They recognize each other's abilities and dedication to justice. For instance, Superman respects Batman's ability to fight crime without powers, and Batman respects Superman's selfless use of his powers.
One interesting storyline could be them teaming up against a new supervillain that neither can defeat alone. They combine their unique skills, Superman's super strength and flight with Batman's detective skills and gadgets.
One great example could be a fanfiction where Batman and Superman team up to face a new, powerful villain that neither could defeat alone. They combine their unique skills, with Batman's strategic mind and Superman's super strength, to outwit the bad guy. Another example might be a story that delves into their friendship during their off - time, like when they have a friendly sparring session to keep each other on their toes. There are also fanfictions that explore how they support each other through personal crises, like when Superman has doubts about his place on Earth and Batman is there to offer his grounded perspective.
In the fanfiction, Batman's brooding and calculating nature contrasts with Superman's more optimistic and straightforward personality. For example, when they plan to take on a villain, Batman will analyze every possible scenario while Superman might just want to charge in and stop the bad guy immediately. This difference in approach often leads to interesting discussions between them.
One of the best moments could be when Batman manages to outwit Harley in a battle of wits. He uses his knowledge of her psychology to predict her moves. For instance, if Harley tries to set a trap using her knowledge of Arkham's layout, Batman quickly figures it out and turns the tables on her.
'A Death in the Family' is a significant story. It was a major event where Jason Todd, the second Robin, was killed. This story had a huge impact on Batman, making him more brooding and determined. It also showed the brutality of the Batman universe and how high the stakes can be for the characters.
In some fanfictions, their 'friendship' is a very twisted one. The Joker might see Batman as his only worthy opponent, so in a sense, that's a form of 'friendship'. He constantly tests Batman, not just to defeat him but also because he enjoys their interactions. Batman, on the other hand, may understand the Joker in a way that no one else does. He tries to stop the Joker's madness but also has a strange connection to him.
He provided a set of best friend avatars that included six sisters. These avatars might be anime styled, size 1200x1200 or 420x420. In addition, there were some other search results about her best friend's profile picture, but they did not provide an answer that completely matched the question.
One of the best Batman novels is 'The Dark Knight Returns' by Frank Miller. It presents a darker and more aged Batman coming out of retirement to save Gotham again.

Another great Batman novel is 'Batman: Year One' also by Frank Miller. It tells the origin story of Batman in a very detailed and engaging way. It shows how Bruce Wayne decides to become Batman, his early days of fighting crime, and how he interacts with key characters like Commissioner Gordon. It's a great read for understanding the roots of the character.
