The Merciless God Ultra Boss (the evolved form of Merciless God Goku Black) is currently one of the toughest challenges in the game. With higher HP, faster attack patterns, new psychic abilities, and a devastating final phase, it can wipe even strong teams in seconds. But with the right units and strategy, it’s very much beatable.
Here’s our complete guide to help you clear it consistently.

📊 Merciless God Ultra Boss Guide
| Phase | HP (Approx) | Key Abilities | Best Counter Units |
|---|---|---|---|
| Phase 1 | 450,000 | Energy Slash, Black Kamehameha | Goku Black, Ultra Instinct, Ice Queen |
| Phase 2 | 1.2M | Rose Vortex (AoE stun), Afterimage | Slow towers + high DPS (Lightning, Inferno) |
| Phase 3 | 3.8M | Infinite Zamasu Mode, Psychic Storm | Full support comp + maxed Goku Black |
Best Team Composition (Meta Setup)
- Core DPS: Merciless God Goku Black (maxed to Tier 3)
- Support: Any strong slow/stun unit + healer
- Backup DPS: Lightning units or high-range towers for consistent damage
- Recommended Synergy: Pair with units that reduce cooldowns or boost damage during stun windows
Step-by-Step Strategy
Early Game (Phase 1):
Focus on rushing Goku Black to Tier 2 quickly. Use cheap towers to hold the early waves while saving for his upgrades. The Rose Vortex stun in Phase 2 is your biggest weapon — place slow towers so enemies stay trapped in the vortex longer.
Mid Game (Phase 2):
This is where most runs fail. The boss starts spawning clones and using wide-area psychic attacks. Position your main DPS in the back with support units in front to tank. Keep upgrading Goku Black — his Tier 3 Infinite Zamasu form is essential for clearing the final phase.
Final Phase (Phase 3):
When the boss enters Infinite Zamasu Mode, the screen fills with projectiles and psychic storms. This is the make-or-break moment. Use all your saved resources to max out your strongest units. The key is surviving the first 30 seconds of the phase — after that, the boss becomes more predictable.
This Ultra Boss is significantly harder than the regular Merciless God Goku Black version we covered earlier. If you haven’t read that beginner-friendly guide yet, check it out here.

Merciless God Ultra Boss is brutal but incredibly rewarding once you master the timing.
