"Anything else?" Dr. Brief asked.
"Build me a gravity chamber," Cabros said, watching Brief closely, fearing a refusal.
"With Earth's materials, 10x gravity is the max," Brief replied.
"My spaceship uses alien metals," Cabros offered. "Can you push it higher?"
"I'll check," Brief said.
Cabros handed over his combat power detector. "Remove the eavesdropper and boost its detection limit."
"This sensor's beyond Earth tech!" Brief marveled. "I'll upgrade it."
"Mr. Brief," Cabros said, "I know my requests seem excessive, but there's a reason."
In early 743 A.K., Cabros explained the Saiyans' plight under Frieza, the Universe's Emperor. To protect Earth, the detector's tracker had to be removed. He framed the Saiyans' conquests as acts forced by Frieza, emphasizing their love for battle, not destruction. He revealed Frieza's betrayal, the destruction of Planet Vegeta, and his immense power, far beyond any Earth warrior. For context, an armed human had 5 combat power, 10 could lift heavy weights, 150 could destroy a city, and 1,000 could devastate a continent. Cabros, as a Great Ape, exceeded 10,000, enough to threaten Earth's survival.
Brief, awed by the cosmic stakes, abandoned any thought of betraying Cabros. Frieza's power was terrifying, and Cabros alone could doom Earth if provoked. To prove loyalty, Brief introduced his wife and ten-year-old daughter, Bulma.
Bulma, bold and curious, approached. "What's your name? What's your plan?"
"I'm Cabros, but call me Leon on Earth," he said. "I'm seeking Master Roshi, the martial arts god, to boost my combat power."
"Why the rush?" Bulma asked. "Earth's peaceful!"
"Peaceful because cosmic powers ignore low-value planets like Earth," Cabros replied. "If they target us, everyone dies, and Earth gets sold."
Cabros refused Bulma's shopping invite, prioritizing training. He knew strength deterred enemies, not provoked them. Goku's power saved Earth from Raditz and Vegeta, not doomed it. Without him, Earth would've fallen. Goku's later guilt was flawed logic or an excuse to dodge Chi-Chi and train.
Bidding Brief's family farewell, Cabros flew to Mount Paozu, spotting Son Gohan poised for battle. Gohan was alive, with six years until Goku met Bulma in the original timeline.
"You're strong," Gohan said, eyeing Cabros's wagging tail. "Are you Goku's kin? I adopted him, thinking he had no family."
"I'm Cabros, a Saiyan like Kakarot," Cabros said. "I mean no harm. I just want to see my clansman and ask you to introduce me to Master Roshi."
"Goku's real name is Kakarot?" Gohan mused. "Son Goku suits him. You're too strong for me or Master Roshi to guide."
"My strength is racial talent," Cabros countered. "I lack proper training methods."
"If you're set on this," Gohan said, "take little Goku to train with my master."
"Agreed," Cabros said.
His arrival sparked a butterfly effect: Goku would train with Roshi six years early, altering the future. In the *Dragon Ball* world, clinging to the original plot was reckless with enough power. Countless near-wipeouts proved strength trumped destiny. Cabros, now in a real world, couldn't afford mistakes. His earlier fake-death plan had flaws but worked. On Earth, he'd seize every chance to grow stronger.
Seven-year-old Goku returned, hauling a huge fish. Taller than his later self, he resembled the Goku who fought Tien Shinhan.
"Are you family?" Goku asked.
"Not quite," Cabros said. "We're Saiyans, your people. I never met your father, Bardock, but he was a rare genius."
"Who's stronger, my dad or you?"
"Bardock was far stronger," Cabros said.
"Then I'll be as strong as him!" Goku declared.
"I'm counting on it," Cabros replied.
With Gohan's introduction, Cabros and Goku reached Master Roshi's island. Roshi welcomed Goku as Gohan's grandson but hesitated with Cabros.
"You're too strong," Roshi said. "I can't guide you."
"My strength is just Saiyan talent," Cabros insisted. "I need your training techniques."
He offered a stack of adult magazines and DVDs, eyeing Roshi eagerly.
"Ahem!" Roshi coughed, feigning sweat. "Since you're sincere, I'll teach you."
Roshi's test of respect was clear. Cabros's overwhelming power could crush even a revived Mutaito, Roshi's master. Yet, Cabros's humility and gifts showed no arrogance. Roshi decided to teach him everything.
From 743 to 744 A.K., Cabros trained under Roshi alongside Goku, mastering Kame-style Qigong, Kamehameha, World-Shaking Palm, Afterimage Fist, and more. Roshi's methods revealed a sophisticated ki system, far beyond the anime's depiction. Cabros's foundation solidified, his strength surging. Compared to a year ago, he could now defeat his past self in seconds, even if his exact combat power remained unmeasured.
