The “Defender” or “Tank” role in Max Battle measures one thing: how many hits you can absorb without going down. Unlike DPS attackers (where output matters), a great tank trades raw damage for sheer survival, letting your team’s Max Meter fill safely. This guide ranks the Top 7 tank picks based on per-boss endurance simulations against the current boss roster.
What “Tank” Means in Max Battle
A tank’s job is not to deal damage — it’s to last long enough that the team’s Max Meter fills and the actual attackers can switch in for the Max Move phase. Three things matter for tanks:
- Endurance: HP × Defense × type resistance. The number of hits you can absorb.
- Type matchup: A tank with type advantage against the boss multiplies its endurance.
- Meter contribution: Tanks with 0.5-second Fast Moves charge the Max Meter twice as fast as 1.0s alternatives.
This guide ranks by endurance (#1) and type matchup flexibility (#2). For meter charge speed specifically, the 0.5-second Fast Move guide is the companion read.
How This Ranking Was Calculated
- Endurance simulation: Time-To-Faint (TTF) per boss at PL50 IV15, averaged across the current Max Battle boss roster.
- Type weakness modifier: Defenders are penalized for any super-effective boss type they’d face.
- Acquisition cost: Non-Legendary Pokémon get a small bonus because the candy curve is less brutal.

The Top 7 Max Battle Defenders

Blissey
Normal — Top endurance against virtually every boss in the rotation. The largest HP pool in the game makes Blissey the universal tank — start with Blissey if you’re not sure who to bring.

Zamazenta (Crowned Shield)
![]()
Unique Wall move grants a free shield at battle start — no other Max Battle Pokémon has this. Combine with Steel-type endurance and Zamazenta is the active tank that also contributes damage.

Zacian (Crowned Sword)
![]()
Triple resistance vs. Dragon-type damage makes Zacian the optimal tank for Dragon-boss windows. Doubles as a top-tier Steel raid attacker.

Gigantamax Snorlax
Non-Legendary candy curve makes Gigantamax Snorlax cheap to build, and its bulk approaches Blissey’s. Slight edge in damage output via G-Max Replenish.

Metagross
![]()
Double resistance to Psychic, plus broad Steel-type resistance set. Cheap to acquire and balanced offensively — wins multi-role battles.

Corviknight
![]()
Steel/Flying gives a unique resistance set; against the right boss, Corviknight can outlast even Blissey on simulation. Easy to acquire and raise with XL candy.

Gigantamax Lapras
![]()
Top tank vs. Water and Ice-type bosses; G-Max Resonance debuffs the boss for the team. Hybrid tank+attacker — placed Top-1 in damage tests vs. Zapdos.

Bottom Line
For tank-role flexibility, a Blissey + Zamazenta + one type-specific tank stable covers nearly every boss in the rotation. Type-match tanks first when you have one available; fall back to Blissey when you don’t.
