The figures in the Heli-Sub all watched in silence as the Anti-Builder controlled and guided the Guardian of the Deep, seemingly making it patrol around the Gateway to Atlantis. Seeing as they were level with the sea floor, Emmet silently hoped that they would go under the creature's sight.
"Do you think he'll spot us?" asked Emmet in a whisper, leaning over to ask Brains.
"Hopefully, he'll just pass us by without giving a second look," whispered Brains, though it was clear in his voice that that question was only something only second to his mind right now.
"How is this Anti-Builder controlling the Guardian of the Deep? No-one could tame that Shark; I tried," said Brains, looking at the others in a hope to get answers.
"Anti-Builder isn't exactly what you would call 'anyone'," said Chase simply, before the others all shared looks.
"Look," whispered Zeon, walking up next to Emmet and pointing out of the window. Laval, Perri and Wyldstyle all got to their feet and approached behind them so everyone could see what Zeon was talking about.
In the middle of the Ocean in front of them, the Guardian of the Deep slowly came to a stop, directly in front of the Portal to Atlantis.
Suddenly, as though out of nowhere and unprovoked, red lightning suddenly arced over the entire, rough-skinned Guardian of the Deep, who let out a deep wail of pain that seemingly echoed through the ocean; and hit the Heli-Sub at full force.
"No…" whispered Brains softly, getting up from his seat and pressing himself up against the glass; his face pressed tightly against the window.
"How could he do that, to such a beautiful creature?"
"He's Anti-Builder; he does what he wants," said Chase simply, gently resting a hand on Brain's shoulder; it appeared that he was trying to comfort Brains, but he was doing a poor job trying.
It was like he wasn't even trying at all.
"But…But," whispered Brains, turning his head around slightly to look at each of the others in the Sub in turn. "How could anyone kill such a beautiful creature? I mean, sure, they can be dangerous, but only if you provoke them."
Emmet looked at Brains softly, a sympathetic look crossing his face, as he slowly shifted around and put a comforting hand on Brain's shoulder; he was doing a much better attempt of comforting than Chase had done.
"Brains…there is no other way to describe it; it's Anti-Builder. H…He does what he wants and thinks he can get away with it. He's doing it with the Oblivion Trinity, and he just did it with that massive shark," said Emmet, trying to tell Brains the truth while trying to be comforting.
"We've got to stop him from doing anything worse; if he gets his hands on all of the Oblivion Trinity, and the Wheel of Oblivion…we have no idea of what's going to happen, but it can't be good," added Laval, stepping up to comfort Brains as well.
Brains looked up at Emmet, before turning to look at Laval, and casting his gaze over to the others in the sub.
"That sounds touching, but we don't have time for comforting," said Chase, who was already in a wet suit, with an oxygen tank on his back and diving helmet in hand.
"How did you get changed so quickly?" asked Emmet, scratching the side of his head slightly.
Choosing not to answer this question, Chase put the helmet on over his head, breathing deeply and slowly now. "We need to get that Crystal to a secured location before Anti-Builder gets at it," said Chase firmly, before he added, "You should all get wet-suits on; I'm going to be opening this door."
Emmet quickly said, "Wait a minute Chase, we don't know where the suits are!"
"You've got two minutes."
Knowing from Chase's tone that they weren't going to get a second warning, Emmet, Wyldstyle, Brains, Zeon and Perri all scrambled to get into the wetsuits; Laval had chosen to stay behind and keep an eye on the sub.
After agreeing to contact them if anything changed and promising not to touch anything, no matter how flashy the buttons looked, Brains allowed Laval to keep an eye on the sub while they went out to stop Anti-Builder and get the Third Oblivion Crystal.
"Alright, ready?" asked Chase, though by how he turned around quickly without waiting for anyone to respond, he obviously didn't care if the others were ready or not. When Laval had quickly sealed himself away so that he wouldn't drown when the door would open, Chase slowly turned the handle and with a firm tug, pulled the door open.
All of the pressure that had built up outside the Heli-Sub suddenly gave in when the door opened, sending highly-pressurised water into the interior of the sub. This sudden force flung Emmet across the interior, pinning him to the walls. The others would have met the same faith, if they had not grabbed onto something the second before Chase opened the hatch.
Not stopping to make sure that the others were alright, Chase, bubbles coming out from the oxygen connection with his mask, slowly swam out from the Heli-Sub.
Emmet looked behind him once he had managed to get off from the wall to look at Laval through the glass; Laval gave him a reassuring look, before Wyldstyle lightly tapped Emmet's shoulder.
"C'mon, we better catch up," she said, her voice muffled slightly through the water and the mask, bubbles escaping when she spoke. Emmet nodded and slowly began swimming after Wyldstyle and the others.
Glancing back and seeing that Laval had sealed the Heli-Sub up again, Emmet quickly swam after the others, with Chase and Brains leading them towards the Gateway to Atlantis. Though before they reached it, Brains broke off from the group.
"I'm going to see to the Guardian," said Brains, before he quickly swam downwards, where the body of the Guardian of the Deep was currently resting, lifeless.
"We'll go on the Third Crystal," said Chase, before he quickly swam towards the Gateway. Zeon and Perri went with Brains to help him out with investigating the Guardian; leaving Chase, Wyldstyle and Emmet to get to the Oblivion Crystal before Anti-Builder.
"Can you guys see him?" asked Wyldstyle, looking around slowly as she tried to swim and look around at the same time.
"We lost sight of him from the point the Guardian was killed," said Chase simply, looking around carefully as his swimming slowed slightly.
Emmet looked around cautiously and nervously, finding it disturbing that the place they were swimming through was once filled with life, and it was now completely barren of life; the only thing left being the odd fish that swam by and the sea weed.
Movement to his right, hidden behind several bits of ancient ruins, caught Emmet's attention and he stopped quickly, looking around quickly.
"Guys, I thought I saw something," he said, hoping they heard him over the radio.
"We don't have time for that; we've located the Third Crystal," said Chase over the radio, static filling the communication after he spoke.
Emmet glanced back where he had seen the movement seconds ago, before he unwillingly turned and started swimming after the other two again.
When he arrived at the others, he was greeted with the sight of a partly collapsed cave entrance, which had several large chunks of rubble partly blocking the entrance. But from what they could see from the light was cast from above, they could see it.
Sitting on a stone podium, near the entrance, was a dark green Crystal; the Third Oblivion Crystal.
"We've got the Third Crystal," said Emmet excitedly, before he quickly swam towards the entrance of the cave.
"Emmet, wait!" said Wyldstyle.
But it was too late; Emmet was about to react the cave when suddenly, a shard of red light shot past him, flinging the Master Builder off and back into the others.
Wyldstyle managed to catch her boyfriend before he went off into the distance, and the three of them righted themselves just in time to see what happened.
Anti-Builder was standing on the edge of the cave entrance, the dark red light under his hood still glowing, despite the murkiness of the water.
"You never give up, do you?" growled Anti-Builder, his voice echoing around the water and against the bodies of the three.
"We're not letting you get away with this, Anti-Builder!" said Emmet hotly.
"You talk too much," grunted Anti-Builder, before he slowly pulled his arm from behind his back; revealing that, in the time Emmet had taken to be righted, he had already swiped the Third Oblivion Trinity Crystal.
Emmet and Wyldstyle tried to swim towards Anti-Builder to grab the crystal from him, but was stopped when they heard several terrified screams over the radio.
"Brains! Zeon, Perri!" shouted Emmet, before seeing movement from the side.
From the side, over the ruins of the Gateway, was the Guardian of the Deep; though now, there was something else added to the top of the shark's body. There was what appeared to be a control device, flashing red at the top, with the shark's eyes a dark red.
"We thought it was dead!" exclaimed Brains.
"I didn't know sharks could play dead," muttered Wyldstyle.
"They can't," growled Anti-Builder, before he suddenly jumped upwards through the water, grabbing onto the Guardian of the Deep's fin as it passed by.
Anti-Builder quickly got onto the top of the Shark as it swam away from the group.
"No…" said Emmet softly, watching Anti-Builder, along with the Third Oblivion Crystal, swim away.
Though before anymore words were exchanged, a blinding white light suddenly appeared in the middle of the group, temporarily blinding them. Once the light had vanished, they noticed that there were fewer of them than there were before.
Emmet and Wyldstyle were gone.
