Pinsir

Pinsir is Pokemon with potential. Bug-type moves have effectiveness against Grass, Psychic, and Dark-types. Pinsir can see use in Alakazam and Mewtwo raids, although it is not close to being optimal. Pinsir’s Fighting-type movesets can contest Tyranitar, Snorlax, and Blissey, but Machamp and many other Fighting-types do this job much better.

Defensively, Pinsir has bad stats and a poor typing. Fire, Flying, and Rock-type attackers are common, which prevent Pinsir from being threatening. 

Best PvE Offensive Moveset

• Bug Bite is superior to Fury Cutter and should be paired with X-Scissor for Bug-type offense.

• Rock Smash can pair with Superpower, or less preferably, Close Combat if no Fighting-type Pokemon are available. 

• Submission* is inferior. 

• Vice Grip is not a good move. Use your TM here.

Best PvE Defensive Moveset

• On defense, Rock Smash does over double the DPS of Pinsir’s other fast moves.

• X-Scissor is fast and frequent, but ineffective against Pinsir’s counters.

• Vice Grip is overall just a slightly worse version of X-Scissor.

• Superpower has better coverage than X-Scissor but is more reactable.

• Submission* is a downgrade due to its inferior base power. 

• A 1-bar charge move like Close Combat is poor due to Pinsir’s low bulk.

With somewhat below-average Damage per Turn and high Energy per Turn, Fury Cutter is a great move for launching Charged moves quickly and furiously. Close Combat  and Superpower are both powerful Fighting-type moves that provide wide coverage, don't cost a lot of energy, and apply self-debuffs. However, they're risky to use and could leave Pinsir vulnerable to be farmed.
