In the heart of a dense jungle, a tribe of anthropomorphic white tigers gathered for a sacred ritual. It was the day when Kael, the eldest son of the chief, would receive the mighty power of the great tiger, a rite of passage for him.

Kael stood tall, his eyes focused on the golden insignia of the great tiger in front of him. The tribe echoed with chants, heightening the tension. He felt the power pulsating from the insignia, ready to bond with him.

Suddenly, a figure darted from the crowd, pushing Kael aside. It was Kael's younger brother, Kiro, who was consumed by jealousy and craved the power meant for his older brother.

The tribe gasped as Kiro touched the insignia. A blinding light enveloped him, and the power of the great tiger transferred into him. He roared, his body growing in size, muscle, and fat.

"Look at me, brother!" Kiro bellowed, his voice booming. He flexed his massive muscles, taunting Kael and the tribe. His laughter echoed through the jungle, a haunting sound that promised chaos.

But as the minutes passed, Kiro's laughter faded. His body continued to grow, his muscles now obscured by the expanding fat. Panic flickered in his eyes as he struggled to control the swelling size.

"I can't... I can't stop it!" Kiro cried out, his voice echoing with a painful roar. The tribe watched in horror as Kiro kept growing, his body bloating beyond control.

"Kael... help me!" Kiro pleaded, his voice filled with desperation. But Kael could only watch in silence, his heart aching for his brother.

Kael's eyes hardened. He knew the power of the great tiger was not to be tampered with. It was a blessing for the deserving and a curse for the unworthy.

Kiro's roars echoed through the jungle, his plea for help drowned in his uncontrollable growth. His body kept expanding, the skin stretched taut over the massive form.

Suddenly, with a final, agonizing roar, Kiro exploded in a burst of blue flames. The tribe gasped, their faces reflecting the bright light of the explosion.

When the light faded, there was nothing left of Kiro but a scorched mark on the ground. The tribe was silent, the air heavy with shock and grief.
