He rushes at his foes with considerable force, using his own body (with a yellow aura around) as a weapon, inflicting a high amount of damage.
Broly uses this technique twice when fighting Goku, Gohan and Future Trunks on New Planet Vegeta. Specifically, he first uses it right at the start of the fight, when he attempted to run Goku and Gohan over (with Goku using rapid movement to shove Gohan out of the way), and he uses it again against Gohan and Future Trunks.
