My family, the Avengers ( An Avengers/ Percy Jackson Crossover)

Avengers Arc: Manhattan and Memories

Percy followed the team on to the exit. They had prepared for the fight and were ready to defend this planet, though they had no idea what they were up against. Clint might've had some inclination as to what Loki was planning, but Percy only cared about t his father. "Tony, let me come, please! I wanna help!" 

"No, you're not coming," Tony lifted the faceplate of the suit to look Percy in the eyes. "I don't want you to get hurt any more than you already are, got that? If you try to sneak on to the ship and I catch you, no PlayStation and movies for a month."

"What?!" Percy yelled in protest. "What if I just stay on the ship! I won't leave!"

"Ask again and say goodbye to your skateboard and DS," Tony closed the door to the air deck and waved bye to him before flying to the jet where Clint and Natasha had started to lift off. Percy starred angrily through the window of the airtight door. As much as he wanted to help Tony, he knew that if he was there he would instead try to find his father. Maybe he would be enough to bring his senses back. 

With a grunt and his eyes closed, he stomped his foot enraged. When he opened them again, there were the remnants of verdigris wisps around him. The black steel-like metal of the quinjet shocked him when he realized where he was and whose voices he was hearing. Quietly he turned in the small corner he teleported in and looked through the holes in the support beams.  Tony was closer to him because he was towards the exit, ready to fly off and start the fight. Steve was towards the front with Natasha and Clint as they flew threw the city. 

The drop door opened and Tony flew out. When it closed and everyone turned their attention back to what they were doing, Percy gathered up as much magic as he could and hoped he teleported to where he wanted. There was a loud pop and Percy fell to the ground. His breath short and heart racing as if he had just run ten-thousand miles. Yes, Percy mentally cheered as he looked around from behind the wood decoration curtain thing Tony had. Percy could see the bar and the couches clearly.

He moved to the other side to try and get a closer look through the windows, hoping to see what was going to happen without getting caught. Instead, he saw his father on the terrace looking over the midday skyline, his uncle flying onto the landing pad he had installed shortly after upgrading the tower. Together they both walked inside on opposite sides of the room. Loki was just a few feet away from where Percy stood hidden. Tony on the other side walking in behind the bar. 

"Please tell me you're not going to appeal to my humanity," Loki spoke casually as Tony grabbed a bottle of whiskey from the countertop. But with his signature banter, he simply replied with, "uh-actually, I'm planning to threaten you."

"You should've left your armor on for that." 

Tony shrugged his shoulders and poured ice into a glass cup. "yeah, it's seen a bit of mileage. You've got the uh- blue stick of destiny. Would you like a drink?"

Loki shifted his weight to one foot and looked at Tony with a stern look. "Stalling me won't change a thing."

"No, no,no-threatening. No drink?" Tony placed the bottle down and Percy looked questionably at his uncle keeping a causal conversation with Loki. Though he didn't know the plan, he had guess was to try and talk Loki into telling him his plan, but then he saw Tony put the bracelets of his prototype of Mark seven. They kept the talk going as Tony walked out from behind the bar describing his new friends, even if Tony refused to admit he has new friends. It got a bit too heated when they stood face to face and Loki tried to use his scepter on Tony.

One thing led to another and Tony was thrown out the window. It took everything Percy had in him not to run out and yell for his uncle. Mark seven flew out from the elevator shaft, almost knocking Loki down, and crashed into the window where it dropped to catch up to Tony's rapid descent. But when Loki walked to the edge to (hopefully) the dead body of Tony Stark on the pavement far below, he flew up, covered head to toe in the newest armor, and spoke to the man in green. "And there's one more person you pissed off! His name is Phil."
