Pokémon GO Hub ranks Gigantamax Cinderace as its top counter, followed by Gigantamax Charizard and Dynamax Darmanitan. Build around your strongest available attackers, but make room for defensive and healing support: a Max Battle team can bring up to three Pokémon, and a knocked-out trio stays down until the battle ends.
The announced Rillaboom event took place on August 1, 2026, from 2:00 to 5:00 p.m. local time. That date has passed, and the official announcement does not give a return date.
What is Gigantamax Rillaboom weak to?
Rillaboom is pure Grass type. Pokémon GO Hub lists five weaknesses: Bug, Flying, Fire, Ice, and Poison. Use attacks of one of those types, and check the type of the Pokémon’s Max Move as well as its species. For Dynamax Pokémon, the Fast Move determines the type of the Max Move, according to the guide.
Best Gigantamax Rillaboom counters
These are Pokémon GO Hub’s recommended attackers, not official guarantees. The best choice for your team depends on what you have powered up and can use effectively.

| Pokémon | Recommended attacks | Why consider it |
|---|---|---|
| Gigantamax Cinderace | Any Fast Move; G-Max Fireball | Pokémon GO Hub’s top-ranked attacker. |
| Gigantamax Charizard | Any Fast Move; G-Max Wildfire | The guide’s second-ranked attacker. |
| Dynamax Darmanitan | Fire Fang or Incinerate; Max Flare | The guide’s third-ranked attacker and a Dynamax alternative. |
| Dynamax Moltres | Specific moves not stated in the guide summary. | Another listed attacker. |
| Dynamax Flareon | Specific moves not stated in the guide summary. | Another listed attacker. |
| Dynamax Ho-Oh | Specific moves not stated in the guide summary. | Another listed attacker. |
The guide specifically gives moves for the first three picks. For the other listed options, confirm their current move typing and Max Move in-game rather than assuming a particular set. A strong, already-invested counter can be more practical than building a nominally higher-ranked pick from scratch.
Build a team with attacker, defender, and healer roles
Pokémon GO Hub recommends treating the battle as a team-role problem instead of selecting three damage dealers by default. Its suggested three-Pokémon lineup is:
Rank #2
- The Pokémon TCG: Mega Evolution—Pitch Black Elite Trainer Box includes 9 Pokémon TCG: Mega Evolution—Pitch Black booster packs and 1 full-art foil promo card featuring Zarude.
- This also comes with 65 card sleeves, 40 Pokémon TCG Energy cards, and a player’s guide to the Mega Evolution—Pitch Black expansion.
- You will also get a competition-legal coin-flip die, 6 damage-counter dice, and a plastic coin.
- You will also find a collector’s box to hold everything, with 6 dividers to keep it organized and a code card for Pokémon Trading Card Game Live.
- Vespiquen (Dynamax): defender or tank.
- Blissey (Dynamax): healer.
- Gigantamax Cinderace: attacker.
For a four-Trainer group, the guide suggests two attacker-focused teams, one defender team, and one healer team. This is specialist strategy advice, not a required formation; adapt it to the Pokémon available to your group.
Max Battle mechanics that affect your plan
The Pokémon GO Help Center says you can bring up to three Max Pokémon into a Gigantamax Battle. If all three are knocked out, they remain unavailable until the battle ends. A knocked-out player can cheer, contributing to the other Trainers’ Max Meter.

- Max Guard reduces damage from the opposing boss.
- Max Spirit heals the user and allies.
- Leveling Max Moves requires Max Particles and Pokémon Candy.
These mechanics make survival and team support relevant alongside damage. If you have a defender or healer available, consider whether that support is more valuable to your group than a third attacker.
Battle tips for Gigantamax Rillaboom
- Start with a fast Fast Move. Pokémon GO Hub recommends opening with a Pokémon that has a very fast Fast Move to charge the Max Meter, then switching to an attacker for the Max phase.
- Use a super-effective Max attack. Prioritize Bug, Flying, Fire, Ice, or Poison damage, and verify the Max Move’s type—especially on a Dynamax Pokémon.
- Watch for the single-target attack warning. The guide reports that Gigantamax bosses use two charged moves from their move pool: one affects all active Pokémon, while the stronger single-target move can be dodged by swiping when its warning appears.
- Keep support moves in mind. Max Guard can reduce incoming damage and Max Spirit can restore health for you and allies, according to the Help Center.
- Cheer if your team is knocked out. If all three of your Pokémon faint before the battle ends, cheering still helps fellow Trainers charge their Max Meter.
Pokémon GO Hub lists Rillaboom’s possible Fast Moves as Scratch and Razor Leaf, and its possible charged moves as Energy Ball, Grass Knot, Earth Power, Drum Beating, and legacy Frenzy Plant. Move pools can change with game updates, so treat that list as guide-reported rather than a guarantee for every encounter.
Rank #4
- Pokémon TCG: Mega Evolution—Pitch Black Booster Bundle contains six booster packs from Pokémon TCG: Mega Evolution—Pitch Black.
- This is a great option for getting into the new Choas Rising expansion.
- A great gift for the Pokémon collector or player in your life.
