Amoonguss

Competitive Strategy

Amoonguss is a Grass/Poison defensive support Pokemon with Grass/Poison typing. Grass/Poison STAB lets it pressure Water, Ground, Rock, Fairy, and Grass targets. Its role depends on the format, but the type-chart job is clear: use its useful resistances, immunities, or offensive pressure to force the opponent into predictable answers rather than treating it as a generic switch-in. Stats, ability choice, and legal moves still decide how aggressively it can be positioned. The weakness profile is the central part of the page: Amoonguss is 2× weak to Fire, Ice, Flying, and Psychic. Amoonguss has no type immunity. These numbers come from the standard type chart for Grass/Poison, so ability effects, field effects, Terastallization, or format-specific rules can change an individual turn without changing the baseline matchup. Do not leave Amoonguss in front of a super-effective attacker just because it has a useful offensive move in return. To use Amoonguss well, bring it in through a resisted move, a pivot, a forced switch, or a revenge-kill window rather than repeated raw entries. It appreciates teammates that cover Fire, Ice, Flying, and Psychic pressure and create safe entries. To counter Amoonguss, preserve Fire-type attackers, Ice-type attackers, Flying-type attackers, and Psychic-type attackers and pressure it before it can turn its matchup into momentum. Use the type chart first, then account for speed, bulk, ability, recovery, and revealed coverage before committing to the exchange.
