This one is one fo my craziest ideas, the three of them are based in mytological greeck monsters and in the constellations which has their names

CESTAR is based in Cetus, the marine monster [link]

HYDRALAXY is based in the Hydra, the nine headed snake [link]

COSTELADON is based in Ladon, the hundred headed dragon [link]

the three are supposed to came from the space, fallen with the stars, during shooting star's nights, that's why their bodies are made from space darkness (Black body) and star's light (White circular marks). During the night, their bodies mix with the darkness, making their white marks shine, giving them the look of constellations

This are the most hard not-legendary pokemon to caught in Kroel region, in fact, you'll be able to have just one CESTAR from the Kroel Spatial Center when you achieve to defeat The Elite Fours (mostly like BELDUM)

whit them Stardust and Star Pieces became useful, at least more than just expensive items to sell at pokemarts, and if they dont have their respective items at the proper level, they wont evolve.

Hope you like them
