Fabio adjusted his gym bag, his eyes reflecting a mix of admiration and determination as he looked up at Víctor. "I can't wait to get started, bro. Maybe one day, I'll be as strong as you." Víctor chuckled, his muscular frame exuding confidence. "With dedication and hard work, you will. Let's hit those weights!"

Fabio felt the sting of their words, his resolve faltering until Víctor appeared, his presence an unspoken promise of protection. "Leave him alone," Víctor said, his voice firm and unwavering. The bullies dispersed, and Fabio looked at his brother with gratitude. "Thanks, Víctor. I don't know what I'd do without you."

Fabio picked up the collar, its surface shimmering with a mysterious energy. "This looks ancient, Víctor. I wonder what it does." Víctor shrugged, intrigued but dismissive. "Probably just a trinket. Let's focus on our training."

As Fabio slipped the collar around his neck, a surge of power enveloped him. In moments, his frame transformed, muscles bulging beyond anything Víctor had ever achieved. "Whoa... this is unreal!" Víctor looked up at his now towering brother, his own physique diminished. "Fabio, what happened?!"

Fabio flexed his muscles, reveling in his newfound strength, while Víctor trailed behind, his spirit dampened. "Look at this, Víctor. I've never felt better!" Víctor forced a smile, hiding his growing sadness. "Yeah, it's impressive..."

Fabio paused, his heart heavy with regret. "Víctor, I've been so blind. I miss the way things were. Can we change it back?" Víctor nodded, hope flickering in his eyes. "Let's try, together."

The world shifts once more, returning to its familiar state, but with Víctor now more powerful than ever. Fabio looked up at his brother, tears of gratitude in his eyes. "I'm sorry, Víctor. Thank you for everything." Víctor enveloped him in a warm embrace. "It's okay, Fabio. We're brothers. We'll always have each other's backs."
