Good grass-type moves in Pokémon games would include attacks such as Solar Beam, Frenzy Plant, Leaf Storm, Petal Dance, Power Whip, Wood Hammer and Seed Flare which are all attacks that hit with a base power of at least 100 however other attacks that are powerful as well would include ones such as Leaf Blade, Petal Blizzard and Energy Ball which hit with a 90 base power.
Catterpie, Roselia, Scyther and many many more grass type Pokemon can learn bug type moves.
Rock, Ground, and Water-type Pokemon are weak against Grass-type moves. This means Grass-type moves can deal twice the damage to the listed types.
