Holy Light Grenade (神裂光弾 Shin Retsu Kōdan, lit. God Rending Light Bullet) is a combined energy ball team attack used by Goku Black and Future Zamasu and by Fused Zamasu occasionally. It is also a precursor to Holy Wrath.
When used by Goku Black and Future Zamasu, they both charge their Black Power Balls, whether for Black being the standard one or Divine Retribution as a Super Saiyan Rosé. Whether they raise it up or just fire it, it will combine to either an orange sun-like sphere or a bright purple energy sphere, again depending if Black is in his Rosé form or not. Once launched, the Holy Light Grenade will turn into a meteor and explode on impact, inflicting a massive amount of damage.
In the manga, Fused Zamasu uses this attack against Goku and Vegeta in attempt to finish team off, which was to no avail. He uses it in another attempt to finish Goku off, which Vegito blew off before he could throw it.
