One interesting plot twist is when Ant - Man discovers that Thanos has a hidden vulnerability related to the Pym particles. Ant - Man then uses this knowledge to his advantage, turning the tables on Thanos during their encounter. This plot twist adds a lot of depth to their relationship in the fanfiction.
A great plot twist in certain Thanos and Ant - Man fanfictions is that Thanos actually respects Ant - Man's tenacity. Instead of just trying to destroy him, Thanos offers Ant - Man a place by his side. Ant - Man has to then decide whether to side with the mad titan or stay true to the Avengers. This creates a lot of moral and ethical dilemmas for the character and makes for a very engaging read.
One possible plot could be that Ant - Man, using his size - changing abilities, sneaks into Thanos' lair to steal the Infinity Stones. He shrinks down to microscopic size and evades all of Thanos' defenses. Once he gets the Stones, he has to figure out how to get them to the Avengers without being caught by Thanos' minions.
One interesting plot twist could be that Iron Man discovers a hidden power within his suit that can counter the Infinity Stones. Maybe it was something he unknowingly built into it long ago.
In this fanfiction, a really interesting plot twist could be that the person they kidnap is actually related to a powerful being from another dimension. So, when they kidnap this person, they unknowingly open a portal to this other dimension. This would lead to all sorts of chaos as strange creatures start coming through the portal, and Ant - Man and the Wasp have to figure out how to close it while dealing with the kidnapped person's family from the other dimension.
A really cool plot twist would be if Batman manages to steal all of Thanos' Infinity Stones and use them against him. This would completely turn the tables. Or perhaps there's a plot twist where Batman uses his detective skills to uncover a secret weakness of Thanos that no one else knew about. Maybe it has something to do with Thanos' past or his family, and Batman uses this knowledge to his advantage in the fight.
One creative plot twist in Ant - Man Hope and Scott fanfiction could be that Scott actually has a hidden power related to the Quantum Realm that he's unaware of until a crucial moment. Maybe it's the ability to control time on a small scale while in the Quantum Realm, which completely changes the dynamic of their missions. For example, he could use this power to reverse a bad situation during a heist that went wrong.
In this fanfiction, a plot twist could be that Ant - Man teams up with an unexpected ally during the fight against the Kree Sentry. This ally could be a character from another part of the Marvel universe who has a unique ability that, when combined with Ant - Man's powers, gives them the upper hand against the Sentry.
A plot twist might be that the snap doesn't completely get rid of Thanos. Instead, it splits Thanos into multiple versions of himself, each with different levels of power and different personalities. Spider - Man then has to face not just one, but several Thanos - like entities. Also, the snap could have unforeseen effects on the Infinity Stones. Maybe they scatter across different dimensions, and Spider - Man has to retrieve them to prevent a greater catastrophe, all while still dealing with the remnants of Thanos.
The inside story of Ant - Man and Thanos is quite complex. Ant - Man's ability to shrink and grow gives him a unique perspective in the battle against Thanos. In the story, Ant - Man was in the Quantum Realm when Thanos snapped his fingers. His absence from the main universe during the snap and his subsequent return played a crucial role. His knowledge of the Quantum Realm also became a key factor in the fight against Thanos as it provided a potential way to reverse the damage caused by the snap.
No, Ant-Man didn't single-handedly defeat Thanos. Thanos is often too strong for one hero to handle, and it takes a team-up of various characters to stand a chance against him.
They have very little direct connection in the comics. Thanos is a major cosmic villain, while Ant-Man is more focused on Earth-based adventures.
