Out of the four Gigantamax Pokémons that are making their returns this weekend in the Replay: GO Bigger event, Gigantamax Gengar seems to be the odd one out. It technically wouldn’t belong here, since Gengar was not part of the original GO Bigger event in October 2024, although one can always argue that it could be considered a part of it, as it made its debut just a week after that during the Halloween Events of 2024.
The beloved ghost of the Pokémon Tower in Gen 1 games is also the odd one out because it is by far the most sought-after G-Max Pokémon of the 4 this weekend, far ahead of the Kanto Starters that appear alongside it.

Nearly 18 months since its debut, Gigantamax Gengar and its G-Max Terror continues to top the damage dealing chart in Max Content as both a Ghost-type and a neutral-type damage dealer due to its crazy high ATK value. It also sees a very niche use as a tank, which is surprising due to its abysmal DEF and HP value.
Gigantamax Gengar as an Attacker: Dominant & Well-Futureproof
Gigantamax Gengar deals Ghost-type damage through G-Max Terror, and with a base ATK of 261, together with the damage multiplier due to its Gigantamax form, we are looking at a Pokémon with the highest ATK value not just among the four Pokémon returning this weekend, but one of the highest figures in the entire Max Battle roster.
The Ghost-type attacker leaderboard is, frankly, not a competition, with only Gengar and Sableye being the two names that are currently available in the current Max meta, and the latter couldn’t hold a candle to our Gigantamax ghost. Even within a broader pool, when put in comparison with other Dark-type damage dealers (since both Ghost and Dark are super effective against Ghost and Psychic,) Gengar still leads with a 13% gap vs. the best Dark-type damage dealer at the moment i.e. Gigantamax Grimmsnarl.
Looking ahead, the future does bring some competition, but Gengar will forever be the #1 Ghost, and even #1 Dark-type attacker if you only use it to deal super effective damage. On the Ghost side, Blacephalon (315 ATK) is the most threatening arrival – but even it falls 6.1% short of Gengar’s Gigantamax-adjusted damage. On the Dark side, Hoopa Unbound (311 ATK) and Darkrai (285 ATK) will eventually enter the meta; but again, neither can surpass G-Max Gengar’s damage output.

Gigantamax Gengar as a Tank: One Exceptional Niche
Gigantamax Gengar is not a tank – let get this out of the way first.
With only 149 DEF and 155 HP, Gengar has the poorest tanking capability of the four returning GMax Pokémon; and truthfully, no one gets Gengar so that it can tank anything. It is a ghost, everything thrown at it will go straight through its body and hit the trainers in their faces…
That said, Gengar’s Ghost/Poison dual typing creates one genuinely exceptional defensive niche that deserves attention: Fighting-type attacks.
Ghost-types don’t just resist, but are completely immune to Fighting attacks in the main series games; and in the context of Pokémon GO, this immunity translates into a triple resistance that pushes Gengar high up the tank list in the most bizarre way possible. Gengar ranks #2 among all released Dynamax and Gigantamax Pokémon against Fighting-type attacks, behind only Dynamax Lugia who unfortunately does not have a 0.5s Fast Move to make it a viable tank and Max Meter charger. More tellingly, it ranks #7 among every Pokémon in the game against Fighting, meaning even when the full future roster is accounted for, Gengar remains a near-elite Fighting resist. This is a remarkable result for a Pokémon with 149 DEF.
Elsewhere, against Normal, Bug and Poison-type attacks, Gengar ranks #6, #9 and #11 respectively among released Pokémon due to its double resistance. For everything else, even if Gengar resists it, its poor DEF and HP do not warrant using it as an effective tank in those cases.
Gigantamax Gengar Ghost/Poison Ranking by Type-Resistance |
|
| Type | Ranking (as of 2026) |
| Fighting | #2 |
| Normal | #6 |
| Bug | #9 |
| Poison | #11 |
| Fairy | #25 |
| Grass | #35 |
Verdict
Gigantamax Gengar is the most straight-forward investment recommendation of the four Pokémon featured this weekend. It is the #1 Ghost attacker in Max content that even deals higher damage against any Dark Pokémon out there in the mode. Its Fighting immunity adds a specific but genuinely valuable tank niche on top of its primary attacker role. Furthermore, Ghost-type attackers hits neutral damage on the majority of Max bosses, making Gengar with 261 ATK an amazing neutral damage dealer as well.
If you have never built a Gigantamax Gengar, this weekend is the most important event on the card for you. If you have one but at suboptimal IVs or under-levelled Max Moves, the three-hour window is worth spending heavily on. The shundo chasers among you already know what to do. For everyone else: Gengar should almost certainly be your first stop when the first minute the event starts on Saturday.
