Diglett

Using Diglett in a Playthrough

The Diglett line is built around extreme Speed and strong Ground-type offense rather than durability. Dugtrio can outspeed much of the opposition and use moves such as Dig and Earthquake to remove Electric-, Poison-, Rock-, Fire-, and Steel-type targets before they retaliate, while its Ground typing grants a complete Electric immunity. In Kanto, Diglett's Cave makes the line available immediately before Lt. Surge and can provide a particularly strong answer to that Gym, with Dugtrio sometimes appearing there already evolved. Its extremely low HP and physical bulk make mistakes dangerous, however, so Dugtrio performs best when it can secure a knockout rather than exchange attacks.

Diglett in Competitive Pokémon

Dugtrio has one of the most distinctive competitive histories among early-generation Pokemon because of Arena Trap, which prevents many grounded opponents from switching. This allowed Dugtrio to function as a dedicated trapper and eliminator, using its exceptional Speed to remove specific weakened or vulnerable targets that would normally escape into a teammate. Smogon describes Dugtrio as a prominent trapping Pokemon across multiple generations, with Arena Trap becoming powerful and controversial enough to be banned in several competitive environments. Outside formats where Arena Trap is permitted, Dugtrio's limited bulk and only moderate offensive strength greatly reduce its niche despite its excellent Speed.

Diglett in Nuzlockes

Dugtrio can be extremely useful in Kanto Nuzlockes because Diglett's Cave provides a highly reliable Ground-type encounter immediately before Lt. Surge, allowing the line to neutralize one of the game's major early Electric-type battles. Its excellent Speed also makes it a strong cleaner and helps compensate for its fragile defenses by allowing it to attack first. Community FireRed and LeafGreen analyses disagree somewhat on its overall tier because its low bulk can cause sudden deaths, but they consistently recognize its Surge matchup, Ground typing, and access to strong Ground STAB as important strengths. Dugtrio therefore rewards careful matchup planning more than defensive play: when it has a safe offensive advantage it can be excellent, but it is poorly suited to absorbing unexpected attacks.

Diglett spends almost its entire life underground, normally traveling through shallow tunnels and exposing only its head above the surface. Its skin is extremely thin, and exposure to bright sunlight heats its blood and causes it to weaken. It feeds on roots and vegetables while digging, which can make it an agricultural pest, but the same tunneling tills and aerates soil and its waste enriches the ground, so some farmers deliberately welcome it. Diglett also uses abandoned Onix burrows and has been found living beneath forests and even inside hollow trees.
