However, just as Lott was comforting Nino and watching Ash and Tobias enter the arena through the light screen-
Deep underground, thousands of meters below Z-City.
The depths beneath this city, located in the most remote area of Planet Terra, were experiencing continuous, slight tremors.
And they were becoming more and more frequent, more and more frequent.
In less than five minutes, the slight trembling rapidly escalated into a magnitude 10 earthquake!
"Wh-What's happening!?"
Uesugi Futaro, who lived in Z-City due to his family's poverty, felt the ground shake and stumbled to the ground.
The eggs he had just bought from the supermarket shattered all over the floor.
Uesugi Futaro was about to pick up the eggs that weren't too badly broken and could still be eaten.
"Lott... tt..."
Faintly, Uesugi Futaro felt like he heard something.
Boom-
Just as he was wondering, the city's landmarks cracked drastically, and skyscrapers collapsed amidst the tremors.
The ground also tilted diagonally towards both sides.
"Eeeaaaah!"
Uesugi Futaro stumbled. Although he tried to grab the railing by the street-
He was, after all, just an ordinary person with no special abilities.
As the ground continued to tilt, he fell into the bottomless chasm.
At that moment, a green figure flew over, but it was a step too late and failed to catch Uesugi Futaro.
"Ah!"
The newcomer sighed heavily. The narrow-eyed young man he was carrying comforted him:
"Nail-san, it's not your fault. Th-Thank you for saving me."
Shirogane Miyuki, held single-handedly by Nail and now graduated from Shuchi'in Academy, tried to reassure him.
"Lott... tt..."
The voice came again.
Causing Nail and Miyuki Shiro's expressions to change drastically.
"That voice just now... it came from underground!?"
Nail's face changed dramatically.
Shirogane Miyuki blinked a couple of times. "D-Did it just say... that person's name?"
Rumble!!!
Just as the two were curious, the entire surface of Z-City completely collapsed.
A large number of monsters of various shapes and sizes crawled out of the fissures like madmen.
The sight left Nail, a Namekian, and Shirogane Miyuki, an ordinary Terran, stunned in mid-air.
'Th-There are this many monsters underground!?'
However, at this moment, these monsters lacked their usual ferocity.
They were more like ordinary humans facing a natural disaster, fleeing in panic, scared out of their wits.
"Aaaah- Run! Run!"
"Orochi-sama is going berserk!"
"Speaking of which, is that still Orochi-sama? I think it looks more like that alien Lott killed a year ago..."
"You still have the mood to think about that? Run!"
Weak Wolf-level and Tiger-level monsters were directly crushed into pulp by the collapsing buildings.
The stronger Demon-level and Dragon-level ones weren't much better off.
Something underground was terrifying them this much.
"Run! Run!"
A monster with a cat's face but standing on four limbs, with a humanoid body, swiftly fled among the collapsing buildings.
Nail's eyes sharpened, as he remembered this monster.
It was the Dragon-level monster who had recently been continuously attacking heroes, Nyan.
With a cat's personality, it didn't directly defeat heroes.
It preferred to torture heroes to death like playing with mice.
At that moment, a large hand, almost entirely composed of sludge, like a biochemical monster, emerged from the depths of the chasm, accurately grabbing the Dragon-level monster, Nyan.
Amidst its incessant wails, it was dragged into the abyss.
"What... what was that just now..."
Even Nail, with a power level over ten thousand, was stunned.
…
Deep within the Monster Association's underground.
The biochemical giant hand that caught Nyan dissolved its target halfway through dragging it, absorbing it as fertilizer into its own body.
And the giant raising this hand was none other than Cooler, who had been killed by Lott!
No!
Perhaps it was more appropriate to call him [Bio-Cooler] now.
Because the current Cooler's body was festering, with almost no intact skin.
When he opened his mouth, a rotten hole on his cheek revealed the teeth and putrid tongue inside.
Extremely disgusting.
"Lott-tt-!"
Bio-Cooler spoke again, uttering the name.
The heroes gradually arriving on the surface heard it clearly.
'It really was shouting 'Lott'!'
Standing half a mile away from Bio-Cooler, Psykos, the founder of the Monster Association, hid behind a broken wall.
Her beautiful face was even twisted due to excessive tension and fear.
'What a terrifying guy! Even dead, his will could devour Orochi. But it seems he's lost his reason, only left with endless hatred for Lott?'
Psykos peeked out slightly to observe Bio-Cooler.
To be precise, it was the product of merging Cooler's corpse with [Monster King] Orochi after she found it.
She thought this would create the ultimate, strongest monster capable of rivaling the Super Saiyan.
But Psykos clearly underestimated the power of the Frozen Demon Race.
Even though Cooler was dead, his head blown off-
After the bodies merged, his consciousness actually devoured the living Orochi!
Although he lacked all his former reason, only left with the obsession to kill Lott-
But... it was still terrifying enough!
"LOTT!!!"
After sensing the Super Saiyan's ki, Bio-Cooler could no longer suppress the resentment in his heart, letting out a roar that shook the planet.
Boom-
Finally, the entire Z-City exploded completely.
Endless shockwaves mixed with fragments of steel and walls from buildings flew out in all directions.
Tatsumaki, who had rushed over, quickly raised her small hands, trying her best to prevent the explosion from spreading further.
"Tatsumaki, careful!"
A combat robot emitting Dr. Kuseno's voice blocked in front of Tatsumaki.
Tatsumaki hadn't realized what was happening.
She only vaguely saw the combat robot in front of her get sent flying.
And something was rushing towards her at extreme speed.
Too fast! Can't see!
"Masenko!"
A golden energy ray shot from the side, blocking in front of Tatsumaki.
But it was still easily sliced through by the opponent.
However, it bought time, which was enough.
Tatsumaki's body contorted strangely and was sucked into a bizarre alternate dimension.
Before Tatsumaki could even voice a 'What is this place?' exclamation similar to Patrick Star's-
The scene before her twisted again.
She was released.
"Cough! Cough!"
Ishigami Yu beside her coughed violently.
Under Tatsumaki's astonished gaze, he said breathlessly:
"I'm getting used to teleporting myself... but teleporting others... this is the first time."
"You are... the one who gave the Dragon Ball to Lott..."
Before Tatsumaki could finish, Genos suddenly spoke:
"This enemy is quite unexpected."
Tatsumaki sharply looked up. When she saw the opponent's true form clearly, her pupils shook with fear.
"Co... Cooler... B-But..."
'What's with this zombified form!?'
"Picked up by some unknown force and modified into this, right? No wonder we couldn't find Cooler's body no matter how hard we looked... Speaking of which, is he even usable for cells now?"
Genos said, deeply conflicted.
