Vivian lands next to Tony, who remains out of sight, just in time to hear Loki's outburst. "I am a king!" He says.
"Not here! You give up the Tesseract! You give up this poisonous dream! You come home.
"I don't have it. You need the cube to bring me home, but I've sent it off I know not where.
The hammer flies back into the blonde man's grasp. "You listen well brother. I…" The man is knocked off the mountain by a giant ball of fire, Tony looks at Vivian who just shrugs before he flies after the man.
"I'm listening." Loki says. Vivian waves her hand, causing vines to come up from the ground, wrapping around Loki's hands and feet.
"Stay put." She says before going after Stark.
The man crashes into the forest, Iron Man lands nearby, his helmet opening up. Vivian doing a "superhero landing" right beside him. The man stares at the pair, "Do not touch me again!"
"Then don't take my stuff." Tony sasses back.
"You have no idea what you're dealing with." The mans warns.
"Shakespeare in the park?" Tony asks. "Doth mother know you weareth her drapes?"
"This is beyond you, metal man, tony girl." The man says, causing Vivian to make a face. "Loki will face Asgardian justice!"
"Once he gives up the cube, he's all yours." Vivian says, crossing her arms and jutting out a hip.
"Until then, stay out of our way." Tony warns. His helmet comes back down, and he turns to walk away. In one quick motion, the man pulls back his hammer and throws it, hitting Tony and throwing him into a tree. "Okay." He says. Vivian's fists begin to glow, ready to fight.
The man raises his hand, the hammer flying back into it. He swings it, summoning some sort of electric energy. Before he can, Tony stands up and shoots a blast of energy from his hand repulsors, throwing the man to the man back. Vivian swoops her hands up, successfully wrapping the man in vines. He looks at her, then the vines, confused. A second later he stretches his arms out, ripping the vines. She looks to Loki, worried to see if he could break out as well, but he remains in the same spot, smirking. It was like he was enjoying this. Vivian conjures a ball of fire, throwing it at the man and knocking him into a tree. Payback for Stark, she thought.
The man kneels on the ground, summoning the hammer to him and raises it to the sky. Vivian looks up in amazement as his hammer summons thunder and lightning. He points the hammer at Vivian. She stands there, hoping she can absorb the hit, but at the last second, Tony jumps in front of her in the Iron man suit. "How about that?" Tony says, then holds up his hand repulsors and fires a huge stream of energy at the man, pushing him to his knees. The men then fly towards each other and then upwards.
They crash right back down after a few seconds, smashing every tree in their path, Vivian notes as she flies after them. Tony yanks the man up, who in turn grabs the arms of the Iron Man suit and begins to crush them. Tony quickly charges the boost and shoots a beam of energy into the man's face. The man falls back, giving Tony the chance to headbutt him with his helmet. The man retaliates, headbutting Tony back, sending him flying across the forest. After scuffling a bit more, Vivian steps in. She walks right back up to the man and grows vines from her hands, right as the man lifts his hand to summon his hammer, Vivian shoots the vines outward and wraps them around his hands and pulls him closer. She knees him in the stomach, causing him to double over, then headbutts him much like Tony did. What she didn't anticipate, was this ending the same way. The man reels back and headbutts her, once she is knocked out, he throws her aside before going after Tony.
From behind some trees, Steve sees this and decides it's time to step in. As the blonde man is ready to attack Tony again, Captain America's shield ricochets off both of the men, stopping them. They look up and see Steve standing on top of a fallen tree, the shield back in his hand. "Hey, that's enough." He comes towards them, "Now, I don't know what you plan on doing here."
"I've come to put an end to Loki's schemes!" The man replies.
"Then prove it! Put the hammer down."
"Um, yeah, no! Bad call! He loves his hammer!" Tony says, causing the man to knock him back with the hammer.
"You want me to put the hammer down?" The man leaps high into the air, raising his hammer. Steve crouches down and holds up his shield. The man brings the hammer down onto the shield, causing a massive explosion of light and a shockwave that blows away anything standing within a mile of them.
Tony and Steve stand up, all of the men looking at each other. "Are we done here?" Steve asks, making his way over to Vivian who is starting to stir. He picks her up bridal style and proceeds to carry her to where the quinjet landed. "Let's move out."
