The theme of redemption can also be found in some Tim Drake Joker fanfiction. There could be a scenario where the Joker has a moment of change, or Tim tries to find some good in the Joker. However, this is a more complex and less common theme compared to the others as the Joker is usually seen as an irredeemable villain.
I really like 'Tim Drake: A New Beginning'. In this fanfic, we see Tim Drake dealing with the aftermath of some major events in the Batman universe. It's a more character - driven story that focuses on his growth and how he overcomes his inner demons. It's a very engaging read.
I really like 'Tim Drake: The Lost Days Fanfic'. It fills in the gaps of his past and gives more depth to his backstory. It's a great read for those who want to understand Tim better in the Batman universe.
One possible scenario in this fanfiction could be that Tim Drake initially looks up to Batman from afar. He might be in awe when he finally meets him, perhaps during a crime - fighting situation. Tim could be trying to prove himself to Batman, showing off his detective skills that he has honed over time.
There are several great authors in the Tim Drake Batman fanfiction world. 'RedRobinFan' is an excellent one. Their stories about Tim are filled with detail and they really capture his essence as a character. 'BatmanFanatic789' is also great. They often write long - form fanfictions that explore Tim's journey in great depth. Additionally, 'GothamStoryteller' has some really unique takes on Tim's story within the Batman universe.
Perhaps it's due to a psychological breakdown. Batman has endured so much trauma over the years. The constant fight against crime, the loss of loved ones, and the never - ending battle with his inner demons could all take a toll. One day, he just snaps. His mind can no longer handle the pressure, and in an attempt to escape from his own tortured self, he subconsciously adopts the persona of the Joker, as the Joker seems to have no such moral and emotional burdens.
One great Tim Drake Joker fanfiction is 'The Joker's Influence on Tim Drake'. It delves into how the Joker's presence in Gotham affects Tim on a psychological level. It shows Tim trying to understand the Joker's motives while also struggling with his own sense of justice.
In some fanfictions, it could be due to personal growth. Tim Drake might have outgrown the role of Robin or the shadow of Batman. He may want to explore his own identity and capabilities independently, away from the Bat - family. He could feel that staying with Batman is holding him back from reaching his full potential as a hero.
