Dragon Ball Super: Season 4, Episode 19

4 - 19: Final Judgment?! The Supreme God's Ultimate Power

Immensely more powerful while possessing the abilities of his components, Merged Zamasu displays his power by devastating the Earth in the process while overpowering Goku and Vegeta. Future Trunks decides to rejoin the fight, but he is also overpowered while using his Galick Gun to hold off Merged Zamasu's Holy Wrath attack. Vegeta aids Trunks with his Galick Gun and overpower Merged Zamasu's attack, though he survives unscathed. Vegeta barely saves Future Trunks from a deadly attack before knocked out as Merged Zamasu charges a second attack before Goku intervenes with his Kamehameha.
