Fearow

Fearow can operate as an early-game budget Flying Type attacker, but honestly it's just not worth investing any stardust in. Its performance is terribly lackluster, and it provides no niches. Even Pidgeot, the Route 1 beginner bird of beginner birds, can Mega Evolve to give it a niche that's arguably worth dropping Stardust in. Unfortunately, Fearow is just plainly one of the worst Flying Types of Generation 1/Kanto.

Best PvE Offensive Moveset

• Peck and Fly make for Fearow's best offensive moveset. Just about everything else can be ignored.
• Sky Attack and Drill Peck both fall behind.

Best PvE Defensive Moveset

• Peck is effectively Fearow's strongest fast move on defense thanks to STAB, and it also has higher energy gains.
• Steel Wing provides solid defensive damage and can punish Ice and Rock Types
• Drill Run maims the majority of Rock, Electric, and Steel Types that would seek to prey on their advantageous matchups Vs. Flying Types
• Twister* is great on defense due to its low energy cost and great neutral coverage.
• Drill Peck comes out frequently and has STAB, but can leave Fearow easily walled if combined with Peck.
• Sky Attack and Fly are stronger, but they take longer to charge up, while Aerial Ace is Drill Peck, but worse.

Fearow's Fast Moves are the primary reason for its lackluster performance. Although Steel Wing doesn't benefit from STAB, its parameters far outclass Peck's.

Fly is actually quite strong with STAB, and is Fearow's main Charge Move with a moderate energy cost. Drill Run is valuable for its coverage, especially against Fearow's weaknesses to Electric and Rock Pokemon, as well as common Steel-types. Aerial Ace is a viable option over Fly as it costs slightly less, but it deals significantly less damage.. Sky Attack, after receiving two nerfs, has now fallen to a point where Fly outclasses it both in terms of damage AND energy. Twister is just bad.
