One exciting plot could be that the Guardians and the Avengers have to team up to stop a powerful cosmic villain who is collecting powerful artifacts from both Earth and other planets in the galaxy. The Guardians' knowledge of the galaxy and the Avengers' understanding of Earth could be combined to track down the villain.
Well, for Tony Stark, he might become a bit more laid - back around the Guardians. The Guardians' carefree attitude could rub off on him. He may start to make more jokes and not be as uptight about his technology and plans.
One exciting plot twist could be that the Infinity Stones have a different origin in this fanfic. Maybe they were created by an ancient race that both the Avengers and Guardians have to discover together. This would force them to work closely and share their knowledge.
One idea could be that the Infinity Stones are scattered across different planets again. The Avengers and the Guardians have to team up to find them before a new villain does. Maybe Thanos has a long - lost relative who is out for revenge and wants to use the Stones' power for destruction.
I think the meeting between Thor and Groot would be fascinating. Thor, being an Asgardian god, and Groot, a sentient tree - like creature. Thor might be initially confused by Groot's limited vocabulary ('I am Groot'), but as he gets to know him, he would see Groot's strength and loyalty. Groot could also be intrigued by Thor's lightning powers. And their combined strength in a fight against a common enemy would be a sight to behold.
Definitely Thor and Star - Lord. Thor is this god - like being from Asgard, and Star - Lord is a half - human, half - alien space adventurer. Their personalities are quite different. Thor is more noble and straightforward, while Star - Lord is a bit of a scoundrel. But they both have a sense of humor and a love for adventure. They could have some great banter while fighting side by side.
Well, there could be an epic battle against a common enemy. Maybe Thanos somehow returns and the combined forces of the Avengers and Guardians have to use their unique skills to stop him. The Avengers' strength and strategic planning along with the Guardians' out - of - the - box thinking would make for an exciting story.
Well, there could be a huge battle against a common enemy. Maybe Thanos is back again and the combined forces of the Avengers and the Guardians have to use their unique skills to defeat him. For example, Iron Man could team up with Star - Lord to come up with a high - tech plan, while Thor and Drax could be on the front line, using their brute strength.
Another great pairing could be Hulk and Groot. Groot's calm and gentle nature might have an interesting effect on the Hulk. Maybe Groot could help calm the Hulk down when he's about to go on a rampage, or they could team up in a fight and Hulk could use Groot as a sort of living weapon. It would be a very unique dynamic.
Black Widow and Nebula would make for an interesting pair too. Both are strong female characters who have had a rough past. They could bond over their experiences of being in the shadow of more powerful male figures in their respective groups. And they could also team up to take on some of the more dangerous enemies, using their stealth and combat skills.
