Forretress

Forretress isn’t a fortress as the name would suggest. This Pokemon has very limited use in the metagame. On offense, its fast move has zero synergy with its charge moves and its low Atk stat is plain unviable. On defense, although Forretress’s Def stat is impressive, it’s crippled by low HP and a fatal double weakness to Fire. There isn’t much value in Forretress and it’s not worth spending stardust on.

Best PvE Offensive Moveset

• Bug Bite is strictly superior to Struggle Bug in every respect.

• Heavy Slam is the only STAB charge move that Forretress learns, and is itself a decent 2-bar move.

• Rock Tomb and Earthquake simply don’t work.

Best PvE Defensive Moveset

• Struggle Bug performs better on defense due to high defensive DPS, though Volt Switch's coverage can also come in handy.

• Heavy Slam and Rock Tomb, both 2-bar moves, are preferred, as they are likely to be used at least once.

• Rock Tomb has coverage vs. Forretress’s biggest enemy: Fire-types.

• Earthquake is not worth mentioning.

Bug Bite deals heavy damage and benefits from STAB. However, Volt Switch can be used for greater energy gains and additional coverage. Struggle Bug is bad.

Rock Tomb is an amazing Charged Attack and covers against Fire-type Pokemon. Its Attack debuff synergizes well with Forretress's terrific bulk. Sand Tomb is an underwhelming move, but its Defense debuff and low cost pairs well with Bug Bite's high damage. Earthquake can be used over Sand Tomb to dent bulkier targets. Mirror Shot is Forretress's cheapest option, but its damage is very lacking despite benefiting from STAB. Heavy Slam and Return aren't really worth running.
