After getting his classmates and the villain out of the water, Leviathan came down to investigate the beast further.
He tries talking to it, but it's unresponsive, less like an animal would be, since a normal fish could be understood by him in a simple way, more like the beast wasn't truly alive, artificial in some way.
He takes out one of the harpoons embedded in the beast, ripping out a large chunk of flesh along with it. The beast trashes in pain but is easily contained with water, it then starts to shoot off a continuous stream of water.
Leviathan is able to aim the creature towards the center of the USJ making water rain there, as if it were a flying river. He also analyzes the way the creature shoots water, to understand what he could be doing differently.
From the surface, Karma can be heard yelling, "Leviathan, stop messing with that thing and come out here."
He comes out of the water. "How is your stamina, either of you want some water?" He presents the harpoon towards them, "Fish?" To which they're slightly grossed out.
Bifrost answers "I just used a month's worth of portals, pretty sure I'm out. I will take some water though."
"Well, I'm doing better than Bifrost at least." He also takes some water.
Looking over at the center of the USJ pure chaos can be seen, many of the students and villains are fighting.
Eraser King is fighting against both a big guy with dark blue skin and a beaked face and a scrawny blue-haired guy who seems to fight with his palms or something.
AstroNautilus is fighting against the cloaked guy from before, along with the help of StarLux, Butcher, and Lucifer.
The water raining down is being a great help to the heroes, the cloaked one had to start teleporting them away, so he's having a harder time with his fight now.
"Hey, Bifrost, I'm going to need one last portal, a small one will suffice. At my signal make one from the top of the battlefield towards the lake." Leviathan says while giving her a bracelet made of ice.
"Oh, come on! Urgh, okay, but if I pass out it's you guys' problem"
Leviathan walks on ice towards the giant water stream, he's eating the piece of the beast he got earlier. Karma follows him. Talking over the plan on the way.
They jump in the water stream, being dragged by its current until they're above the battlefield, Karma absorbing energy until he's full.
From above it can be seen how much the cloaked figure is helping in this fight, redirecting people's attacks left and right, keeping villains safe. Overall being the MVP for their side, which makes him the first target.
He knows this, so he redirects several attacks towards Leviathan, who makes the part of the stream underneath them change trajectory midair, changing its form into that of a Chinese dragon made of water, surfing on it through the air.
The cloaked figure then makes a portal right in front of them, no way to turn fast enough to dodge it. Thankfully Leviathan already had something planned for this. "Hydra!" An ice sphere is formed on the dragon's head, standing still against the current, making the water stream split as it hits the ice.
Leviathan is still surfing on one of the heads formed from this, while Karma falls through the water and is then swallowed by a different dragon head, going towards the ground. Making a pincer attack on the cloaked figure, ready to execute what they planned.
Karma makes a fist on one hand and a palm on the other, putting them together as if to make a Chinese salute. As soon as the hands touch all the energy he had contained is released by his fist and then reabsorbed by his palm. It then goes around and repeats the process.
In a single second, it is as if hundreds of impacts happened continuously, the dragon opens its mouth as the shockwave is then directed towards the cloak, making it look like a "Dragon's Roar!!!" Leviathan and Karma scream in unison.
The shockwave hits the cloak, traveling through his portals and hitting everywhere he is at once, being able to hit him no matter where he is or teleports the attack. The pieces of his cloak that were flying around suddenly converge and then collapse into themselves, being seemingly gone.
When Karma hits the ground he absorbs the impact, storing it for later.
Above the battlefield the dragon's head that Leviathan was riding explodes once again into a continuous stream of ice spikes falling towards the fight, melting into harmless water when hitting a student.
As Leviathan is falling he screams, "Lucifer! Throw me a spear" Then breaking the ice bracelet with Bifrost, giving her the signal. Lucifer does not hesitate to give all he's got on this attack.
The spear goes through the portal directly into the lake, instantly making the whole thing boil and quickly expand over a thousand times as it turns to steam, covering the entire USJ in a thick fog.
The last of the water that was shot by the beast is sent towards the ground underneath Leviathan making a giant ice pillar that he stands on. The inside of the pillar being water that is being pressurized.
Overlooking the USJ he can see that most of the weak villains have already been taken out by the dragon's roar, the heat from the spear, and the ice rain from before.
Leviathan puts what he learned from the beast earlier to good use, making sniper out of water, and shooting highly pressurized water at several of the villains that were still up.
It is then that a portal opens up above Leviathan, "Go get him, nomu" can be heard coming from the other side as the beaked humanoid comes out to attack him. He was already expecting something of the sort, so he just dives into the pillar, turning where he was standing, into a spike heading for collision with the nomu.
The nomu punches forward, not caring about getting hurt, the force of the attack destroys the entire pillar, but Leviathan is able to mitigate the damage by cushioning himself with water. The pillar being destroyed releases the pressure that was building inside it.
Hundreds of water jets are launched at the nomu, it's able to resist most of the damage with its thick skin and regenerate the rest, although its regen is slowed by the cold. But there isn't much it can do about the knockback, being kept in the air by the constant barrage of jets.
As the jets begin to pile up more and more damage on the nomu, more of them begin to pierce it, coming out of the other side and falling down as tall and thin ice pillars, making a whole forest of them. Hundreds of ice shards float through it making constant collisions.
Leviathan then greatly decreases the size of the fog, pulling all the villains that were left to his location, all the mid-level villains are unable to resist the pull of the fog, being dragged directly underneath where nomu was.
The nomu won't be kept there for much longer as the pressure starts to lessen, it's able to send a punch at where it thought its target was, but in actuality ended up hitting the villains that had been dragged there instead.
Leviathan readies himself to fight the only villains left, the strongest one. He makes a sphere of pure water around himself, freezing its edge to make a shield. He then pukes up some of the blood that he got by eating the beast's flesh earlier.
The environment is entirely in his favor, the dense fog making the visibility almost nonexistent for everyone but him, the ground being completely wet, spikes of ice all around the air, and sounds of impacts could be heard from above the fog.
Then something falls on his shield and begins to howl, some sort of giant wolf with giant vials of green liquid on his back. Leviathan wastes no time putting the blood on a statue of ice and sending that towards another of the villains, making the wolf go after it.
The nomu hits the ground immediately dashing and punching at Leviathan, the shield is shattered and Leviathan is sent flying toward another villain, a katana-wielding swordsman with a clear resemblance to Nero.
The villain winds up to unleash a swing at Leviathan, but he manages to use the fog to slow himself down, making a block of ice out behind him, and turning himself midair to jump away from the swing before it can do severe damage, but still getting cut on his back.
He then makes the bloodied statue go toward the nomu, and throws two spears of ice towards him to boot, one behind the other. He then pulls himself toward the ground and begins sliding towards the nomu.
The wolf jumps at the statue, ripping it to shreds right in front of the nomu, who punches toward the spear to destroy it, hitting and launching the wolf away. Leviathan slides underneath the wolf, attaching a rope of water to it.
The second spear will be blocked by the nomu's palm, but before it makes contact 'Hydra' is used to split it, bypassing the arm and hitting the nomu in the eyes. The wolf has its eyes, ears, and nose covered by water to seal its senses.
The wolf is flying at the swordsman, who easily dodges the beast, dodging through it with short-range teleportation, but as to rope finishes extending, it contracts in equal force, launching the wolf at the man's back. The water around its nose is removed, leaving it to smell his target's blood on the blade, attacking what he thought was Leviathan.
Leviathan slides underneath the blind nomu, putting his hand on its back, freezing all the water that was trapped inside it after the regeneration and using it to completely trash his insides, freezing the wounds to prevent regeneration.
From above a woman clad in golden armor slices through the fog, quickly dashing and grabbing Leviathan by the throat. As she thought she had already won Leviathan begins to speak, "Yeah, I think it's already charged enough." Leviathan covers himself in pure water.
A loud rumbling can be heard coming from above, as huge amounts of electricity rain from above, hitting all the villains that were trapped inside of the fog. The ice that was above the fog had been making collisions for a while now, building static electricity, and creating a thundercloud.
Leviathan is protected from it as pure water is not conductive, the rest of the villains are in the opposite situation being in extreme humidity.
The wolf falls down and doesn't get up, the nomu is completely charred and having difficulties with regenerating, and the woman is standing without moving, her grip on Leviathan loosened.
He quickly dashes away being dragged by the frog, as the woman gets a second wind and starts to sprout giant glowing wings.
The swordsman on his last legs begins to transform into a demonic figure, sending slashes everywhere, destroying the top of the USJ, and the ice above them and dispersing the fog completely.
He then goes back to his human form, very hurt. He slashes at the air, ripping it to make a portal.
As Leviathan is dashing away he is suddenly enveloped completely by the cloaked figure. He smiles as Karma proceeds with the plan, releasing all the energy he has into the cloaked figure. But alas, it's too late to stop him from getting Leviathan.
Leviathan is teleported very far away, all the way in the middle of a desert. Judging by the unfamiliar nightsky, it can be determined that he's been brought somewhere on the other side of the world.
He begins to run.
