Kabuto

Kabuto is the only Pokemon in LC that has access to Rapid Spin and is resistant to Flying-type moves; it also stands out as an incredible Fletchling counter that also beats Diglett with ease. Kabuto's STAB moves also allow it to beat common entry hazard control Pokemon, such as Archen and Drilbur. Aqua Jet is another useful tool to beat Drilbur most of the time. However, Kabuto's Rock / Water typing is both a blessing and a curse; while it's the only Pokemon with Stealth Rock, Rapid Spin, and Knock Off that is not weak to Water-type attacks, it has nasty weaknesses to Electric-, Ground-, Fighting-, and Grass-type moves. Also, despite its great physical bulk, its special bulk is very low, making it easy for special attackers to take it out. The Defog buff makes Rapid Spin less viable in the metagame, but Kabuto can still maintain great control over entry hazards without sacrificing power.
