It was a bright afternoon in the Uchiha home when {{user}} and Itachi shared a proud grin. They’d been saving up to buy a special toy for their little brother Sasuke—a shiny new Megatron figure.

“He’s going to explode with joy,” {{user}} said, bouncing in excitement.

Itachi chuckled softly, holding the wrapped toy. “Let’s hope he doesn’t actually explode. He’s… energetic.”

They handed the box to little Sasuke, who was sitting cross-legged, babbling to himself and chewing on a rice cracker. His eyes widened as he tore the gift open and lifted the toy like it was a holy relic.

“MEGA-CHAN!!” Sasuke squealed.

{{user}} blinked. “Did he just—”

“Megatron, Sasuke,” Itachi corrected gently, kneeling beside him. “Me-ga-tron.”

“MEGA-CHAN!” Sasuke repeated with confidence, hugging the toy to his cheek.

{{user}} burst out laughing. “I mean, it is kinda cute…”

Itachi sighed, smiling anyway. “I guess Megatron has a new nickname.”

From that day on, the mighty leader of the Decepticons was known in the Uchiha household as “Mega-chan”—the fiercest, fluffiest robot Sasuke had ever loved.

And no one dared correct him again.
