FrostIron

FrostIron is the non-binary ship between Loki and Tony from the Marvel Cinematic Universe fandom.

Canon
As Loki and Captain America fight in Germany, Tony flies in and blasts Loki. He lands and aims his repulsors at Loki, who surrenders. On the Quinjet, Tony and Steve keep an eye on him until Thor shows up and pulls Loki out. Tony follows them, and a fight ensues between him and Thor, with Loki just sitting on the sidelines watching. Then Cap interrupts and they finally get Loki on the helicarrier.

When Loki escapes, Tony comes to the realization that Loki is the kind of villain who wants attention. And he would go somewhere where he could be the center of attention. Tony stops and realizes that Loki would go to Stark Tower, and the rest of the Avengers go there.

Tony arrives at the tower first and sees Loki in his penthouse. He gets out of the Iron Man suit and makes his way inside. Loki asks if he wants to appeal to his humanity, but Tony wants to threaten him. He offers Loki a drink as he makes his way to the bar. Loki tells him that he has nothing to fear since his army is coming. Tony says he should fear the Avengers: Earth's Mightiest Heroes. He lists all the members and tells him that he's made them all angry. That was part of Loki's plan, and Tony tells him it's not a good one, because they're coming for him. Even if they can't protect Earth, they will take revenge. Loki makes his way over to Tony and says that the Avengers will be too busy fighting him and puts the tip of his spear to Tony's chest. It does nothing. He tries to mind control him again, but it doesn't work. Tony jokes about performance issues and Loki throws him across the room. Then out the window. Tony is able to call one of his suits in time and flies back up. He tells Loki that he not only pissed off the Avengers, but Phil as well, and blows him up before going to fight the Chitauri coming through the portal.

Hulk finally slams Loki into the penthouse floor, leaving a small crater. After the Chitauri are defeated, the Avengers corner a beaten Loki in the tower. He crawls out of his crater and sees all the Avengers staring down at him, then decides to take Tony up on that drink. Tony is seen smirking at his comment.

Fanon
Most fans ship them because of their similarities. Both characters have made some morally gray decisions, although Loki tends to be more morally gray than Tony. They also both have snarky interactions with each other and other characters. Some believe that Tony and Loki will be able to bond over their shared family issue, as both characters have tried so hard to impress their fathers, who in turn idolized others more (in this case, Thor and Steve).

On AO3, FrostIron is the most written ship for Loki and the third most written ship for Tony. It is the sixth most written within the Marvel Cinematic Universe tag.
