Falinks

Falinks is an interesting Pokemon that looks somewhat ridiculous in the overworld screen. Its stats and movesets aren't particularly notable, especially considering much stronger Fighting-types that are already in the game, which makes it mostly a dex filler. 

Best PvE Offensive Moveset

• Counter is the ideal Fast Move of choice.
• Rock Smash is inferior. 
• Superpower outperforms Brick Break on offense.
• Megahorn has no use nor STAB. 

Best PvE Defensive Moveset

• Rock Smash boasts higher damage and energy numbers on defense, compared to Counter. 
• Brick Break is fast and spammed frequently on defense, but is a weak move overall. 
• Superpower trades speed for more damage, and is a decent choice for defense. 
• Megahorn can threaten Psychic-type attackers if Falinks hasn't fainted by then. 

A moveset born by exclusion. Rock Smash and Brick Break are horrible, and this is what we're left with. Counter is really good, though, so that's nice.
