Obviously, Tony is one of the main characters. As for the villains, it could be a variety of well - known baddies from the original story universe.
One likely villain could be Loki. He's always up to no good and loves to play mind games, so a card game would be right up his alley. He might be the one who lures Tony into the game.
In this fanfiction, it could be that Tony has a hidden agenda when he joins the villains' card game. He might be trying to infiltrate the villains' group from the inside. So he plays along with their card game, making alliances and enemies within the group as he goes. All the while, he's secretly gathering information to take them down.
In the 'Tony joins villains card game' fanfiction, Tony's presence could completely change the dynamic of the game. Since he is a character with his own moral code, he might try to reform some of the villains through the card game. For example, he could use the game as a platform to teach them about fairness and cooperation. This would create an interesting conflict as the villains are not used to such concepts. Also, his skills and intelligence would likely give him an edge in the game, but the villains may try to undercut him using their underhanded methods. It could be a really exciting story with lots of twists and turns as Tony navigates this new and dangerous world of the villains' card game.
In this scenario, it would be a complete shocker. Tony Stark is a hero, and Thanos is a villain. If he were to join Thanos, it might be because Thanos somehow convinced him that his plan was for the greater good. Maybe Thanos showed him a future where overpopulation and resource depletion were so bad that his 'snap' was the only solution. But this would go against everything Stark stands for, so it would be a very complex and dark turn for his character.
I don't know as I haven't read the novel. But probably some powerful and devious villains would be the main characters.
Friendship against all odds is also a prevalent theme. Despite their differences, Tony and Loki form a bond that defies the expectations of those around them. This bond often becomes the driving force behind their actions as they face various challenges together in the fanfiction.
Sure. Fanfiction writers often like to cross - over different universes. In a 'Tony Stark Game of Thrones' fanfic, Stark may find himself in Westeros and use his Iron Man suit to his advantage. He could end up being a key player in the power struggles, for example, helping a particular house with his technology against the White Walkers. His presence would definitely shake up the political and military dynamics of the Seven Kingdoms.
Well, if Tony Stark joins Hydra in fanfiction, it would be a total chaos. His high - tech gadgets and genius mind would be a huge asset for Hydra. But his moral compass, which is usually in line with the Avengers, would be seriously conflicted. Maybe he would try to reform Hydra from the inside, using their resources for good. Or he could be brainwashed into doing really evil things at first until he snaps out of it.
A plotline could involve Tony Stark joining Hydra to spy on them for the Avengers. He pretends to be on their side, but secretly feeds information back to his old team. Along the way, he has to be careful not to get caught and also has to deal with Hydra members who start to suspect him. This would create a lot of suspense and action in the fanfiction. Also, there could be a plot where Tony tries to change Hydra's ideology from within, using his charm and intelligence, but it turns out to be a much harder task than he thought.
One popular 'Tony joins Loki' fanfiction might be 'Alliances Forged in Chaos'. It's a great read where Tony and Loki form an unexpected partnership and embark on various adventures together. They face challenges from both the Avengers and other Asgardian foes, and the story does a wonderful job of exploring their complex relationship.
