In Pokémon GO Max Battles, a Defender or Tank is the Pokémon that stays on the field longest and safely fills your team's Max Meter. Unlike DPS attackers, the best Max Battle Defender is judged mainly by survival, not damage. This guide ranks the 7 best Max Battle Defenders in Pokémon GO based on per-boss endurance simulations against the current boss roster.
Max Battle Tank vs Defender: What the Role Means in Pokémon GO
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.

Best Max Battle Defenders in Pokémon GO Ranked
1
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.
4
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.
5
Metagross
Double resistance to Psychic, plus broad Steel-type resistance set. Cheap to acquire and balanced offensively — wins multi-role battles.
6
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.
7
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.
