"So that's how it is. I don't know why you don't exist in our world, but since you came from that other world, it makes sense that you know Kakarot.
"But there's something I'd like to ask you. In your world, how strong are the other Kakarot and the other me?"
After hearing Trunks, Vegeta nodded, then turned to Lei Chen and asked curiously.
"In that world, Kakarot and I before transforming into Super Saiyan 4 were about equally strong. Kakarot had a power level of two trillion, while Vegeta had three hundred billion!
"I'm different from them. I can transform into Super Saiyan 4. I'm an exception; otherwise, it's hard to become a Super Saiyan 4 without a power level of at least ten trillion."
Lei Chen explained.
"Wait a minute. Why can't I understand anything you're talking about? How did we get onto parallel worlds?"
Son Goku said helplessly. With his level of intelligence, he couldn't understand what Trunks meant at all.
"Um, Dad, I'll explain it to you later."
Son Gohan looked at Son Goku with some embarrassment.
"Aw, Grandpa's still the same old Grandpa, even after turning into a Super Saiyan 4."
Pan said helplessly.
"Never mind. I don't know what you're talking about, but as long as you're not an enemy, that's good enough."
As Son Goku spoke, he suddenly looked at Lei Chen with a fighting spirit in his eyes.
"Heh, I knew you'd be like this."
Even if Son Goku hadn't challenged him to a fight, Lei Chen would have wanted to trade a few blows with him. Now that he'd successfully transformed into a Super Saiyan 4, Lei Chen naturally wanted to test his abilities.
"Everyone, move farther away. I don't want to accidentally hurt you."
As he spoke, a red glow began to radiate from Lei Chen. His Super Saiyan 4 transformation, brought about by the power of Super Saiyan God, surrounded him with a red aura. It lacked the starry, shimmering divine energy of Super Saiyan God, but still carried its power.
A terrifying aura spread across the entire planet. For thousands of kilometers in every direction, the sky around Lei Chen instantly darkened. Thick clouds hung low, as if they were about to crush everything beneath them.
Deafening thunder and blinding lightning crackled through the sky, filling everyone with dread.
Lei Chen's current state could be described as an incomplete Super Saiyan 4 God.
"What a terrifying aura! He's several times stronger than Baby. They're both Super Saiyan 4, so why is he so much stronger than my dad was?"
Son Goten asked in astonishment, his face full of confusion.
"No. That Kakarot's aura is even a little stronger than Lei Chen's!"
Vegeta said gravely. His power level was the highest among them, so he could sense it most clearly.
"Lei Chen? I feel like I've heard that name somewhere before. I should know him, but it's been so long. Maybe, just as he said, the Lei Chen in this world really is dead."
Vegeta thought to himself.
"Ha!"
An equally terrifying aura burst from Son Goku. A golden beam of light shot into the sky as golden arcs of electricity flickered around him. With a cold expression, Son Goku raised his power to its absolute limit.
His power level of 260 trillion erupted in full.
Seeing Son Goku unleash his full power, Lei Chen didn't dare let his guard down. Son Goku was slightly stronger than he was.
Lei Chen's power level was only 240 trillion, a little short of Son Goku's 260 trillion.
At that moment, Lei Chen moved.
In an instant, Lei Chen had retreated several meters, while Son Goku hovered motionless in midair.
