Goku's Kaio-ken multiplied his panel power level to 180,000; when he unleashed quadruple Kaio-ken, his power level soared straight to 360,000.
Yet, even at 360,000, there was still a massive gap to Zeltron.
Zeltron moved—his feet blurred into a black shadow, vanishing from sight. In an instant, he reappeared directly in front of Goku, launching a punch at blinding speed.
"So fast!"
Goku's face changed; he bent his body in a desperate arc, barely dodging Zeltron's attack.
BOOM BOOM BOOM—
The battle erupted into a barrage of exchanges. Zeltron and quadruple Kaio-ken Goku clashed among the clouds, fists striking and colliding with explosive force, sending shockwaves cracking through the air.
Krillin, Son Gohan, and the others on the ground could only hear the relentless thunder of blows; Goku and Zeltron moved at such velocity, they were invisible to ordinary eyes.
"No, they're so fast—I can't see anything!"
Krillin's eyes darted around, squinting, but he could make out nothing but streaks in the sky.
Son Gohan, using his enhanced senses, shouted:
"I can see some of it! Look there!"
He pointed overhead, where for an instant Zeltron and Goku's fists collided, unleashing a shockwave that radiated out in every direction.
Luckily, the duel was high above; if it happened on the ground, the landscape would have been obliterated.
Zeltron grinned, feeling the strain in Goku as they clashed:
"Amazing—you can actually keep up with my speed!"
Goku's determined face looked almost fierce, but his expression came from the strain—quadruple Kaio-ken was putting immense pressure on his body, making his face flush and veins bulge.
"Thanks for the compliment," Goku said with a crooked smile, "but you're still holding back, aren't you?"
Zeltron smirked:
"Of course ... if I used my full power, I might accidentally kill you—"
'and then my Super Saiyan cell plan would be ruined.'
Goku retreated, flexing and ready to push harder:
"If that's the case, I'll have to force you to get serious!"
He leaped higher, assuming a familiar stance.
"Is that ... ?"
Krillin and Son Gohan stared up, wide-eyed, as a scarlet energy ball formed between Goku's palms.
"Kamehameha wave?"
Zeltron's eyes narrowed, recognizing Goku's iconic technique.
"Kaaamee..."
As Goku chanted, the glowing orb grew rapidly—fist-sized at first, then expanding until its light outshone the sun above.
"HAAAMEEE..."
With every breath, Goku fed more energy into the Kamehameha, causing the ground below to tremble and rocks to levitate from the sheer force. Even the nearby lake churned violently.
Krillin, alarmed, cried:
"Goku, at this power—if the Kamehameha misses Zeltron and hits Namek...!"
At quadruple Kaio-ken, Goku's power level was 360,000; his full-force Kamehameha would be even higher.
Everyone could feel the world shaking from the gathering blast.
Moments later, Goku roared:
"HAAAAAAAAAAA!"
With a mighty thrust, Goku unleashed the attack—the enormous beam blasted downward at Zeltron.
"Master Zeltron!"
"Sir Zeltron!"
Rapp and Toss shouted frantically as the colossal shockwave slammed toward Zeltron.
Zeltron could have dodged easily, but chose instead to meet the force head-on.
He spread his palms toward the sky, bracing himself for the impact as the gigantic Kamehameha beam descended on him.
At impact, Zeltron's body dipped, the ground cratered beneath his feet—
But then, his stance stabilized, and he began to push upward against the blast.
Krillin and Son Gohan watched, stunned:
"No way ... he blocked Goku's Kamehameha wave with his bare hands?"
They knew how devastating a Kamehameha at quadruple Kaio-ken was:
Such an attack could destroy a planet—
Yet Zeltron was stopping it cold.
A feat that seemed supernatural.
What kind of power did it take to block a true Kamehameha with bare hands?
