Vaporeon is the water evolution of Eevee and can literally melt into water, making it nearly invisible in aquatic environments. This Water-type's cellular structure is similar to water, allowing it to detect rain an hour before it falls. The card's "Aurora Beam" attack could reduce opponent's attack power while dealing damage. Vaporeon's elegant mermaid-like design and unique water-melting ability made it popular among collectors who appreciated graceful, mystical Pokemon.
