Hello, I’m Ice Princess [Western Crossover]

Norse Iceborn, the son of the northern ice and the only superpowered person in the world, used to spend his days traveling from place to place to protect his country’s peace. After he transmigrated, he was no longer the only one, but he still traveled from place to place, this time to protect world peace. Aliens invading, high-ranking extraterrestrial races descending, multiple universes overlapping, and timelines falling into disarray. When all of this became his responsibility... - Norse transmigrated. As a superpowered person, he should have been able to get by just fine no matter where he ended up. But... What do you mean someone built a super suit by hand in a cave? What do you mean someone turns green when he gets angry? What do you mean there’s a hammer that can control lightning? What do you mean someone took a drug and got really strong? What do you mean someone mutated after being bitten by a spider? What do you mean aliens are invading Earth?! All right, all right. If that’s how we’re playing, then I’m using a cheat too! - After Norse mastered his superpower, he discovered he could freely control ice and change it into any shape he wanted. When an alien species defeated the Avengers and was about to invade Earth, Norse stood before them again and asked: “Did you defeat the Avengers in this ice form, this water form, or this vapor form?” - After protecting Earth, Norse was battered and exhausted. He decided to leave this chaotic place, when someone suddenly caught hold of his hand. He turned to see a pair of beautiful, captivating eyes staring at him without blinking. The person said nothing, just kept looking at him. All right, he’d had a change of heart. - Note: The protagonist isn’t actually called Ice Hero. That’s just a general description of him. His pairing is with Tony. Theme: When heroism becomes a responsibility
