It's tricky to determine. You might want to check if there are any references or background information available. If it's a common name, it could go either way - real or fictional.
Definitely not. Tony Stark and Doctor Doom are separate entities. Stark is known for his genius in technology and being Iron Man, while Doom is a powerful villain with his own complex motivations and abilities.
Chopper is very much alive in the One Piece manga. The creators haven't written his death into the story. He's an integral part of the crew and their journey continues without that tragic event.
In the vast world of comic books, Tony Stark has never taken on the role of Doctor Doom. Their identities and roles within the comic universe remain distinct and separate.
It depends on the specific fanfiction. Some writers might envision them in a dating relationship before, while others might not. Fanfiction offers a wide range of creative interpretations.
The fanfiction can also add a new dimension to the characters. Chopper's relationship with lemons can show different aspects of his personality. If he's really into studying the lemons, it can highlight his scientific curiosity. And it can create new dynamics within the Straw Hat crew as they interact with Chopper's lemon - related adventures.
Well, one interesting storyline could be Chopper getting involved in a zany adventure on a new island where he discovers a unique type of lemon that has magical healing properties. He then has to protect this lemon from pirates who want to use it for evil purposes.
Well, in the 'Avengers Tony is a God' fanfictions, Tony's character evolution is really interesting. His technological prowess is often magnified to a god - like level. For example, he could have the power to create and manipulate matter at will. This not only changes his relationship with his fellow Avengers but also how he views himself. He may struggle with the newfound power and the responsibility that comes with it, just like in the original stories but on a much grander scale.
