Seadra

The Pokedex has very little information regarding this elusive water Pokemon — the second and final stage of evolution for Horsea. Of all the water-based Pokemon, Horsea is one of the smallest and weakest. On the other hand, the evolved Seadra is a powerful Pokemon that can easily defeat the toughest of opponents. Seadra is capable of swimming backwards by rapidly flapping its wing-like pectoral fins and stout tail.

First appearance: Ash has not yet encountered a Seadra.
