A/N: This is just how I think the Avengers: Infinity Wars should have Thor entrance as.
Inside, half the team were standing with Steve Rogers while on the others with Tony Stark. They were throwing insults back and forth with the Guardians of the Galaxy caught in the middle when suddenly, a whirring sound could be heard from outside. They all walked out there ready to fight when they found a ginormous ship landing on the lawn out front. As it landed, the door opened. Loki and a girl walked out to the bottom. We armed ourselves before Loki spoke up.
"Sorry to disappoint, but I am not here to fight anyone." The girl smacked him in the arm. They stood on opposite ends facing each other. A rock dude and…is that Hulk? They came down and did the same thing. Simultaneously, they turned to face the entrance and bowed. Out came...Thor??!!
"What happened to Goldilocks' Hair?" Tony Stark asked. Thor chuckled as the girl stood up ready to fight. He placed a hand on her shoulder and she calmed down, but not before saying,
"You shall respect the king of Asgard."
"Valkyrie, calm. We're all friends, or allies here," Thor said. [Yes, her name is Valkyrie, I searched and I had thought she had an actual name, because I thought the Valkyries were a group of people, not just her]
"Wait, you became king? What happened to your dad?" Steve asked. Thor sighed and shared a look with his brother.
"He passed away, starting Ragnarok." Thor explained. Natasha Romanova stepped forward and wrapped the God of Thunder in a hug.
"I am sorry Thor," She said, before pulling away to go calm Hulk down into Banner.
"What's Ragnarok?" Tony asked.
"The end of the place Asgard lived in. Yet, Asgard isn't extinct. Asgard is a people, not a place. Asgard is now on Earth." Thor explained. "My older sister, Hela, the Goddess of Death, was part of it, she and Surtur."
"Also, Thor's hammer is destroyed," Loki said bluntly. The Avengers all turned to look at him in surprise.
"Yes, but, I don't need no hammer to control the lightning anymore. I am not the God of Hammers, I am the God of Thunder!" Thor shouted as his good eye lit up in electricity and his hands went up in fists as lightning came and started to flow through his veins. The Avengers all looked at him in pure shock. (hehe, I am very punny! ;p)...(Infinity Wars plot goes here)...
