Starmie, like its pre-evolved form, resembles a sea star. Its main body is violet, but it retains the gold formation on its front. Starmie's red jewel core is larger than Staryu’s and has developed to resemble a cut precious stone. The major change that took place upon evolution to Starmie was the growing of a second star on its back. This second set of arms is semi-attached, being able to spin 360°.
Starmie is a genderless species.
Starmie's central core glows in seven different colors, but typically shows up as red. It can also emit electrical waves from the core that are powerful enough to reach the furthest parts of the universe. It spins the star on its back to propel itself through the water and sometimes to launch itself out of the water and fly through the air for short periods of time. It is through this behavior that Starmie uses attacks like Rapid Spin. Starmie still retains all of the abilities of Staryu including re-growing limbs and firing off energy attacks from its core.
Much like Staryu, Starmie are nocturnal creatures and become active at nighttime. Despite this, captured Starmie have been known for surprising tenacity and enthusiasm during the daytime. It is unknown exactly why wild Starmie are mainly night dwellers, however, there has always been the conclusion that Starmie and Staryu are from an alien planet, implying that perhaps the night sky brings the species some sort of comfort in familiarity. This Pokémon has also been noted to “send electric waves into outer space”. These transmissions have also been referred to as “radio signals”. This is very possibly some type of communication between terrestrial Starmie and their alien relatives. The multi-color glowing of Starmie’s core is also believed to be a method of communication inside the species. Starmie’s core is most commonly seen as red in color, which may be a relaxed or dormant signal as according to the Starmie communication system. The core will go dark if Starmie is knocked unconscious, and will sometimes flicker, similarly to a light bulb.
Starmie are a rare sight in the wild, as they require a Water Stone to evolve from Staryu. Their nocturnal behavior also decreases the chances of one being sighted. If they are ever found in the wild, it is in the deepest parts of the ocean; wild Starmie typically share their habitat with many other Staryu.
Like most Pokémon, Starmie’s eating habits are unknown but it’s very probable it filter feeds considering the Pokémon’s lack of a mouth.
This Pokémon was unavailable prior to Generation I.
