Dragon Ball: Broly is a Billion Points Fierce

While being sent to Planet Vampa, Broly is struck by an attack from Beerus.

His spaceship veers off course and heads for Earth, where he meets Master Roshi.

From then on, Broly makes himself at home at Master Roshi's place-and refuses to leave.

Vegeta: "Damn it! Does that guy Broly even need to train? How the hell is his power level so high?"

Goku: "I've already mastered Ultra Instinct... Why am I still no match for Broly?"

Beerus: "This brat is that little kid from back then? How did he get so strong? Legendary Super Saiyan 3? Uh... Aaah..."

Whis: "Oh my, this Broly is just a billion-bit overpowered..."

The original Broly himself-not a transmigration story.
