Jack, a 25-year-old Earthling man, lived a quiet, comfortable life. With a decent job and no desire for romance, he spent his nights indulging in anime marathons. Alone by choice, he enjoyed spending his hard-earned money on the things he loved—especially new anime seasons.
On one such night, around 10 PM, Jack lay in bed watching anime on his phone. The stress from a long day at work, combined with the soothing comfort of his favorite shows, lulled him into a deep sleep.
But when he opened his eyes again, something was wrong.
Jack was no longer in his bedroom. He stood on a grassy plain between a dense forest and a distant city. Panic rushed through him. This didn't feel like a dream. The air was too crisp, the ground too solid. He pinched his arm—pain. He was very much awake.
He wandered toward the nearby city and, to his growing dread, saw a massive Capsule Corp logo on one of the towering buildings.
"No way..." he whispered, heart pounding. "This... This is Dragon Ball Z."
Realization hit him like a truck. He was in one of the most dangerous anime universes ever created—where power levels shattered planets and death was as common as a fistfight. Jack knew the timeline mattered. If he could figure that out, maybe he could plan how to survive.
Then the ground trembled slightly.
Looking up, he saw a blazing streak across the sky—an object getting larger by the second. His breath caught in his throat. A space pod.
"A single pod... Raditz."
It was the start of the Saiyan Saga. Which meant things were about to get very bad, very fast.
Fear consumed him. As an ordinary human, he wouldn't last a second here. He needed power, and fast.
As if answering his silent plea, a system notification popped into his vision:
[System Activated]
New Objective: Proceed to the nearby forest. Synchronization in progress.
Though wary, he obeyed. In a world like this, a system might be the only thing keeping him alive.
He entered the forest, heart pounding. Moments later, the system chimed again:
[Synchronization Initiating: Demon Tiger Gene Integration]
Warning: Host will experience extreme pain.
Pain exploded through his body. Jack screamed and fell, his consciousness fading as his form began to change.
When he awoke, the world felt different. His senses were sharper. Sounds were clearer. His body was heavy, powerful.
Staggering to his feet, he caught sight of his reflection in a nearby stream—and recoiled in shock.
Staring back at him was a towering, midnight-black beast: over 220cm tall, with powerful hind legs, muscular arms, a long, thick tail, a broad chest, and clawed hands. His eyes gleamed yellow with vertical slits. Black shoulder-length hair flowed behind his feline snout, where long fangs and whiskers twitched with tension.
He was no longer human.
He had become a Demon Tiger

After Jack came to terms with his monstrous new form, a strange sense of exhilaration bloomed within him. No longer a fragile human, he could feel power pulsing through his body—wild, volatile, dark. Every breath he took resonated with energy, like his entire being had become a furnace of strength.
For the first time since his arrival, he felt... safe.
That's when the system chimed in again, its cold mechanical voice echoing in his mind:

Jack read the stats, and a smirk crept across his now-fanged face. With a base power level of 25,000, he was leagues beyond most humans and even early Z Fighters. Raditz wouldn't stand a chance against him. He might even rival Vegeta in his early appearances.
"This... this might actually work," he murmured to himself, flexing his claws.
But he knew better than to let his guard down. This was still Dragon Ball Z—and threats only got stronger from here.
He turned his gaze toward the horizon, where the faint smoke trail of Raditz's pod had landed. Jack had a decision to make:
Hide and train in the shadows? Or step into the storyline and change fate itself?
