What it does
Seed Bomb deals Grass-type physical damage at 80 base power, 100% accuracy, no secondary effects. That's the complete description. Against Power Whip (more power, 85% accuracy) or Wood Hammer (even more power, recoil), Seed Bomb trades raw output for consistency. It never misses. It never hurts the user. It works every time.
It's a single-target move in doubles — you pick your target. Against a field with one clear Grass-weak Pokémon, that precision is useful. You're not locked into hitting the opponent who may be Protecting or irrelevant; you direct the damage where it needs to go.
Who runs it
Torterra (9%) is Grass/Ground and physical-oriented, making Seed Bomb a natural Grass STAB. Torterra is a slow, hard-hitting Pokémon that can't afford to miss key attacks. Seed Bomb's 100% accuracy fits that profile cleanly. The 9% figure signals that High Horsepower and Earthquake handle most of its offensive workload — Seed Bomb shows up specifically when the team needs Grass-type coverage against Water, Rock, or Ground threats that the Ground moves can't hit effectively.
Chesnaught (7%) is Grass/Fighting, and its Fighting moves — Close Combat, Hammer Arm, Drain Punch — handle most of its matchups. Seed Bomb fills the Grass slot for the targets that Fighting coverage misses: Water-types, Ground-types, certain bulky Rock-types. The 7% is low because Chesnaught usually doesn't need Grass coverage, but when it does, Seed Bomb is the honest, unadorned answer.
How to use it
The decision is simple: when this Pokémon needs to deal Grass-type damage and can do it physically, Seed Bomb is the candidate. Primary targets are Water, Ground, and Rock-type Pokémon — all weak to Grass.
For Torterra, the pair of Earthquake and Seed Bomb covers a reasonable spread of types. Earthquake handles most of what it needs, and Seed Bomb is specifically for the Water and Rock matchups where Ground STAB is inefficient or resisted.
For Chesnaught, the split between Fighting moves and Seed Bomb is a clean division of labor. The Fighting side covers Steel and Rock; the Grass side covers Water, Ground, and similar threats. Both slots serve distinct purposes without overlap.
Tips & strategy
Seed Bomb's strength is that it gives you a number you can plan around. With 100% accuracy, your damage calculations before clicking the move are reliable — you don't have to factor in a 15% miss chance or build backup plans around a potential whiff. In high-stakes turns, that predictability is worth something.
Be aware of Grass-type resistances, which are numerous: Steel, Fire, Flying, Bug, and Poison all take reduced damage from Grass. When facing those types, Seed Bomb is not the right move — Torterra's Ground coverage or Chesnaught's Fighting moves will typically serve better. Identifying which opposing Pokémon is actually weak to Grass is the core judgment call for using it well.
Seed Bomb appears in these movesets not because it does anything special, but because physical Grass STAB against the right target is a necessary damage type to carry. It's a role move, not a win condition.
