Shellder

Shellder, the Bivalve Pokémon, is prominently recognized as the 90th entry in the Pokédex and hails from the original Generation I roster, a testament to its role as one of the foundational Pokémon. As a Water-type, Shellder exhibits the classic characteristics associated with its elemental type, including a robust affinity for aquatic environments and a symbiotic evolution into the formidable Cloyster. Its simplistic, yet charming design, characterized by a hard shell and a cheeky tongue, has ensured it remains memorable across decades.

Introduced in the Kanto region, Shellder can be encountered in its natural habitat along the shores and in the waters of the Pokémon world. It plays a modest role in the mainline games, often appearing as a wild encounter or as a Pokémon used by Water-type specialists. Its evolution through exposure to a Water Stone into Cloyster adds a layer of strategic depth for players, offering a significant boost in defensive capabilities and access to more potent moves.

Despite not being a starter or a pivotal plot Pokémon, Shellder's endurance through generations is evident. It has appeared in numerous game titles, from the original Pokémon Red and Blue to more recent iterations like Pokémon Sword and Shield, where it continues to be a staple of the franchise’s aquatic Pokémon offerings. This continuity has helped Shellder maintain a steady presence in the Pokémon ecosystem.

Shellder's simplicity and evolution potential make it a compelling choice for trainers looking to diversify their team with Water-type capabilities. Its ability to learn moves like Icicle Spear and Shell Smash upon evolving into Cloyster ensures that it remains a viable option for players who appreciate strategic battling in both casual and competitive scenarios.
