they steal an old pirate ship

"Run it by me again. Just one more time," Steve asked, still highly confused.

They had made it to Florida and were now at a private dock. Percy had just briefly explained his control over any water vehicle and the Captain was not getting the point.It was understandable. Percy still barely got it.

However, they didn't have a whole lot of time, and every second they wasted discussing Percy's weird powers was another second Annabeth's captors had to hurt her. They did not have time for this.

"We are going to steal a boat, and I'm going to sail us the rest of the way," Percy sighed.

"Ok, but, how are we going to sail it if only you know how to do it?" Steve asked.

Even Piper was getting frustrated now. "He can control the boat! We won't have to do anything! The boat will listen to his will! Oh my gods!"

"But how is that possible!?" Steve shouted.

"How would I know?! I was just born with the freaky powers!" Percy yelled right back, getting fed up with this never-ending conversation.

Jason decided to cut in before things got too out of hand. They had to save Annabeth.

"Guys! This doesn't matter! What matters is that we save Annabeth, and we can't do that if we're stuck here arguing over something that is out of our control," he said.

Percy huffed. "He started it."

Hazel rolled her eyes. "How does Annabeth put up with you?"

"Honestly? No idea," Percy smirked.

"Let's just get going, team. We have a boat to steal, right?" Tony asked.

"Yep. And I think this place has the perfect one for the job." The son of Poseidon then started walking away, apparently following his weird sailing powers.

I guess we're supposed to follow him, thought Piper.

"This is supposed to take us through the most cursed waters on the planet?" Bruce asked, looking the boat up and down.

"Yes. Isn't it beautiful?" Percy said and smiled, running his hand along the side.

Tony leaned over to Frank. "Is he seeing the same boat we are?"

Frank just shrugged, used to Percy's weirdness by now. Honestly, it was a little hard for him to imagine the team taking what was in front of them to Polyphemus' island. It seemed like it wouldn't survive the normal ocean.

To be clear, what Percy was suggesting they take was an old pirate ship, currently on display inside of a warehouse at the dock. It was covered in dried-up barnacles, and the mast was split in half. There were also holes all along the sides. It was a miracle the thing hadn't crumbled already.

"Yes, Tony, I am. This thing will run for me. It doesn't even need to be repaired, I can handle that. The only thing that matters is that it is built to withstand the type of waters we're going out in," Percy said. "We need all the advantages we can get."

Natasha, to everyone's surprise, spoke up, "I think we should trust Percy. If he says it'll work, then it'll work. He's the son of Poseidon, right? Nothing can hurt us while in the ocean. Am I correct, Percy?"

Jason cleared his throat and gave Percy a significant look. The Avengers needed to know that they were basically powerless in the triangle. The older teen looked ready to explain, but Frank spoke before he had the chance.

"Actually, no. The Sea of Monsters is outside of Poseidon's realm of power, hence the name. Percy won't have the same access to his father's domain as he does out here," he said, "So, basically, we're entering a dangerous situation, with no backup, and an inexperienced team. Should be fun, right?"

The Avengers were shocked, to say the least. Not at what the boy had said, but who had said it. As far as they had seen, Frank wasn't as confident as his physical form portrayed. They were wrong. Frank was confident, and his friends were proud of him for it, too. It had been a large transformation from when Percy had first met the son of Mars.

"Well, I think we should start heading out. We want to get as far as possible before the sun goes down, right?" Piper asked.

"Right," Percy nodded.

She wasn't really certain about all of this sailing stuff. Sure, she had been on the Argo II, but that was different than an actual boat. For one, it could fly and was controlled by a gaming console. She hadn't really bothered learning how to actually run a ship for that.

But now, she had to act like she knew what she was doing, and that was scary. The Avengers may put on a confident front, but she saw the insecurities in all of them. Some were harder to find than others, but finding insecurities was her specialty.

They really were going into a completely unknown situation. At least Piper and the Seven had been in this world for a little while, but the Avengers hadn't even encountered a monster before. It would sure be a shock when they were faced with some of the worst ones for their first fights. So, she and the rest of the demigods had a responsibility to be the examples, no matter how much the "adults" liked to point out that it was "ethically wrong" for them to do that.

Ω ♆ Ω

Turns out, the kid hadn't been lying about being able to sail the ship. Tony would be the first to admit that he was skeptical of the structure of the vessel, but he was proved wrong when, after the group had gotten the thing into the water, it had started to magically prepare itself for departure. Not a single drop of water leaked into the interior; it was like the water simply moved around the holes.

It was spectacular!

Before he knew it, the group had settled into the boat and were moving away from the dock. The Avengers were marveling at everything around them, considering that Percy wasn't even steering the thing, and yet it was supposedly moving in the right direction. To add to the shock, the ship's parts were moving themselves. It was not logically possible, and yet there Tony was, watching it unfold like some kind of acid trip.

"This is...amazing," he muttered, leaning against the rail with Leo, who he had taken a certain liking to. They were a lot alike.

The son of Hephaestus grinned, "Right? I told you guys Percy had cool powers. You should see him with Blackjack or Arion. It's wacky, man!"

"Who's Blackjack and Arion?" Tony asked, noting the new names.

"Oh. Right, I forgot. Blackjack is Percy's pegasus, and Arion is Hazel's horse. Percy can talk to them because his father created horses," Leo answered.

And just when the man of iron was getting used to all of this, he was pulled back into astonishment.

Ω ♆ Ω

After a couple hours of mingling and exploring, Percy called the team up to the deck. He had started to feel it a while ago when he knew it was still a distance away, but now he knew that they were approaching the Sea of Monsters.

It was a blank spot for him. Everywhere else, he could feel the ocean's power thrumming, waiting for him to control it. But here, there was nothing. Considering they were in the middle of the ocean, it was pretty obvious what it was. That was how he had tracked the place down without a map. It was his blind spot. He would just follow the blankness like it was the North Star.

Once everyone had gathered, he told them the news, and to say the atmosphere changed was an understatement. What smiles they had had disappeared, and their expressions turned serious.

"It's time, guys. Get ready. The first thing we're going to come up on is Scylla and Charybdis. We have to go through them to get into the sea. Now, I've planned this so that we should hopefully be able to pass through without any problems, but with six demigods' luck, we shouldn't rely on that too much. Charybdis only feeds three times a day, so if I planned this right, we should be able to pass over her without a fuss. Everyone got it? Be prepared for a fight, but don't expect it, please. We don't need any more reasons for the Fates to curse us."

Hazel stepped up, "Should the Avengers help us if we end up fighting something? Or should they just observe how we deal with monsters first?"

"We can handle ourselves," Steve defended.

Jason sighed, fed up with the same old arguments, "Alright, that's it! The Avengers will let us take the lead in any fights we may or may not end up in. They will not do anything without one of our approvals because we have actual experience with these beings. They will not be put on the sidelines, but they will also not be on the front lines. Does that work for everyone?"

Percy sent a thankful grin to his cousin, "Thank you, Jason. And yes, it does."

Jason just nodded in return.

"Alright, gang! Buckle up! Make sure to keep your hands and feet inside the ship at all times, and remember, the sword points away from you. It's showtime!" Leo cackled.

Just as he finished, they entered a wall of mist, which was unsettling to say the least. The temperature dropped almost three degrees as they passed through it.

Percy pulled out Riptide before steering the ship towards Charybdis. Hopefully, if everything went to plan, they would be out of this Hades-forsaken place by sunrise.

But, of course, nothing ever went to plan on a demigod's quest.

Ω ♆ Ω

Maybe it wasn't the best idea for me to come, was Bruce's first thought as he got his first glimpse at a greek monster. He had taken refuge inside the sleeping quarters of the ship, practicing his breathing exercises. He was really hoping this didn't turn into a Code Green. This was definitely not the place to let the Hulk loose.

So far, it had been silent upstairs, so Bruce concluded that it was going good so far. He had researched the Greek and Roman myths before they had left and on the plane, and everything that he could find on Charybdis was not reassuring. It was true what Percy said, that she only ate three times a day, but nobody really knew when those times were. Until Percy, apparently. He had survived the Sea of Monsters, so everyone on this ship had to trust his judgement in everything they did here. Bruce could tell that the other Avengers were struggling with taking orders from a "child." But Bruce had learned to not underestimate anyone on his travels while in hiding. Plus, look up any demigod's name and there was a whole list of accomplishments to find.

If Percy said that he knew when the monster liked to eat, then he knew when the monster liked to eat. It was as simple as that.

So, ten minutes into their first obstacle, and things were going fine. Everyone was eerily quiet, but no sign of Charybdis or Scylla yet. Of course, as soon as someone thought about it, an outline of a serpent appeared in the fog surrounding the boat.

Frank was the first one to spot it. "Guys..." He looked up at Percy. "We have a problem."

He pointed into the fog and Percy cursed. "Oh schist. I knew she couldn't just leave us alone."

The Avengers had figured out that something was coming and were unsure what to do. The demigods seemed to be just waiting like sitting ducks for the thing to attack them, and that was not a good plan. The Avengers don't wait for their opponent to strike first.

"Alright, that's it. I'm going to see what it is," Tony mumbled, activating his Iron Man armor.

"No, Tony! That's not a good-" Piper got cut off as the billionaire flew off, "...idea."

If she couldn't yell at that idiot, she was gonna yell at his teammates. She turned around, prepared to cuss out some idiot "superheroes," but Hazel beat her to it. "What was he thinking?! Why didn't you idiots stop him?! He has no idea what he's getting himself into! That monster is NOT something you guys can handle without our help! Mortalium tam stultus!"*

Natasha appraised the small demigod. She sure was a young spitfire. And from what she had seen already, a powerful one.

"Ok, let's just calm down, alright? Tony should be able to hold his own until we can go save his stupid ass," Leo sighed. Working with mortals was draining.

They were always so brash about things. And yes, coming from a greek, that statement was pretty hypocritical, but it still wasn't a lie. He idolized Mr. Stark's work, but man if only the guy could learn some restraint and he would be perfect.

Just as Leo had spoken, an explosion was heard, followed by a muffled string of curses. Only Tony Stark could come up with those creative swear words, so at least there was proof that the guy was still alive. For now, at least. The group needed to get that soon.

"Alright, hold on! This is gonna get bumpy!" Percy shouted, steering the ship towards the sound of fighting.

He willed the vessel to move faster, and it, of course, obeyed. In his head, Percy was just thinking rush rush rush. They needed to get this fight out of the way and get to Annabeth right after. Percy was praying to any god that would listen for there to not be any more disruptions to their journey. He just had to be confident in his skills. He had done this before, so he knew what lay ahead of them.

And it was going to be a challenge.

Ω ♆ Ω

Tony would deny any claim of him being held in the mouth of a sea serpent by his leg. Cuz that didn't happen. Totally.

But if it did, then the rest of the questing group would have worked together to fend off the monster until they could get away. Percy would've used Riptide to stab the monster in the leg, while Jason flew up and used his gladius to cut open her eye. The rest of the group basically just put on a full-frontal assault until Scylla released their idiotic teammate. Leo blew some fire, Hazel manipulated the Mist so that the Avengers could all see it for what it was, Piper made it loosen its grip with her charmspeak, Frank and Clint released some well-placed arrows, Natasha fired some gunshots, and Steve sliced into it with his shield.

All in all, the thing realized quickly that it was outmatched.

Then, after Tony received a very stern reprimanding by Piper and Steve, the group carried on. They didn't have time to dilly-dally. Saving Annabeth was their top priority.

Ω ♆ Ω

Meanwhile...

"Let me go, you skatá!"* Annabeth screamed, kicking her captor in the knees.

She had been knocked out as soon as they had shadow traveled, so she hadn't woken up until an hour ago. When she had, her wrists and ankles had been shackled to a stone wall with imperial gold shackles. The terrorists had stepped up their game.

There was dim lighting, but from what she could figure out before, she was in a cave of some kind. They had completely cleared out the area around her, so there weren't any visible location markers. That is, until they moved her.

The people who had grabbed her were strong and bulky and covered in black. They had black combat suits with black ski masks covering their features. Stereotypically, Annabeth would've figured the goons to be stupid, but they kept her shackles on and put a sack over her head so they at least has someone smart on their team.

Annabeth was getting really sick of not knowing anything, though.

So that's where she found herself at the moment: as a "defenseless" hostage. It was quite comical, really. Did these idiots really think that she would go quiet?

She felt one of her kicks come into contact with a kneecap and heard a satisfying grunt of pain from one of the thugs. Good, she thought, I hope that hurt.

Then, she was thrown onto the cold, stone floor and forced to hold her head up. The whole situation was so stereotypical that she wanted to laugh. But then she also didn't want to come off as more psycho than her captors, so she kept it to herself.

"This is quite interesting," a voice said, "The prideful daughter of Athena, reduced to a simple mortal's hostage.

The sack on her head was yanked off, so Annabeth spat down at the man's feet, glaring at him with a burning hatred. Taking a quick survey of the room, Annabeth found that she was being held captive on Polyphemus' island. The room was the main room of his cave; the one where she, Percy, and Grover further blinded the cyclops.

"If you had actually gotten me on your own, it might have been impressive, but having to use monsters is just pathetic," she said.

The leader growled and kicked her in the jaw. It didn't have enough power to break it, but it did cause her to bite through her tongue.

Annabeth spit out the blood produced in her mouth, dirtying the man's shiny shoes. The guy would have to do a lot worse than that to scare her.

"Hmm... I like your spirit. It's going to be that much more fun when I break it," he hissed, kneeling down to her eye level.

"I hope you rot in Hades," is all Annabeth responded with.

The guy laughed. ACTUALLY laughed. So, he was a crazy sociopath hades-bent on tearing down the natural order of the universe, Annabeth decided, how nice.

Ω ♆ Ω

Bonus scene!

The group was spending time in the dining room of the ship when all of a sudden, Percy remembered something truly horrifying. Like, beyond disgusting!

"Oh, my gods! Guys!!!" he exclaimed.

Hazel rolled her eyes and said, "What, Percy?"

"Charybdis is my half-sister! Ew ew ew ew ew EW EW EW EW!!!" Percy shouted his answer.

Everyone simultaneously gagged.

(Inside, Steve was starting to get seriously concerned about these kids' chaotic family.)
