Slowbro are physically slightly different Slowpoke. It now has striped, tan belly, three claws on its forepaws, and two claws on its hind paws. It has a Shellder latched to its tail in a symbiotic, almost parasitic relationship. The extra weight on its tail has caused the Slowpoke to become bipedal. As a result of carrying this burden, its special abilities have developed greatly. Through the symbiotic relationship, the latched Shellder grows in a spiral shell instead of a bivalve. If for any reason it loses its Shellder, it will result in the Slowbro returning to its former Slowpoke self.
Since it cannot fish anymore, it now has to catch prey. It is therefore, slightly faster than an ordinary Slowpoke, and is significantly more powerful. The most notable changes in Slowbro's movepool is the addition of physical moves, such as Brick Break, Ice Punch, and Seismic Toss.
Used to dozing off at shorelines and lakesides waiting for fish to bite the tip of its tail, the extra burden of a Shellder turned this Pokémon fisher into a hunter, against its own will.
Slowbro tend to live near ponds, lakes, and seashores. The best place to find them is in Kanto and Johto.
Due to the Shellder on its tail preventing it from fishing, Slowbro grudgingly swims to catch prey instead.
This Pokémon was unavailable prior to Generation I.
