Raticate

Raticate, the Mouse Pokémon, holds the Pokédex number 20 and is part of the original 151 Pokémon from Generation I. As a Normal-type Pokémon, Raticate is known for its impressive incisors and its ability to gnaw through almost anything, a characteristic emphasized across games and lore. While not a starter or legendary Pokémon, Raticate has consistently appeared throughout the series, making its mark as a reliable if not often celebrated companion.

Design-wise, Raticate is a straightforward evolution of Rattata, reflecting a natural progression in the Pokémon universe where small, nimble creatures evolve into more robust forms. Its whiskers, large teeth, and strong hind legs suggest a creature evolved for survival and adaptability, traits that resonate with its in-game abilities such as Hustle and Guts, which increase its attack power under certain conditions.

Raticate's role across the mainline Pokémon games is typically as a common early-game opponent, often associated with the trainers of Team Rocket or found in caves and routes of the Kanto region. Its presence in pivotal moments, such as in Red and Blue versions, makes it a familiar sight for players navigating the original games. It has continued to appear in subsequent generations, maintaining a presence in regions like Johto, Alola, and Galar.

Despite not being a marquee Pokémon, Raticate has endured across generations due to its accessibility and the nostalgia it evokes. Its consistent presence in the series has ensured it remains part of the collective Pokémon memory, a testament to its role as a staple within the expansive roster of the Pokémon universe.
