Item Picture

Item Use This item is used by Salva as her normal pokeball. These pokeballs are only know to her, and have only been seen by her family, the Hiriashi's. When thrown, it does not open, rather, it blasts a neon green beam at the pokemon to capture, and out to let loose, to battle, or for whatever reason.
Other Things To NoteThese special pokeballs are also known to others as telepathic balls, as they have been used this way. With a normal pokeball, when a pokemon is caught in it, they reside in that ball until released from it. With Salva's special balls, the pokemon can travel through the pokeballs, allowing her to throw any one of them and call out a pokemon, at which point, that ball will have that pokemon relocated to it. This was the original use of the ball, as Salva's father and mother both would loose their pokeballs, but there later became a much more valuble use, and set of abilities added by Salva herself.
Perhaps the most prominent was the ability to turn all her pokemon into "fusion pokemon" as was called from many. Like dark pokemon, this ball enhanced their fighting abilities in the same way, however did not steal thei personality, and turn them dark. One could say all of Salva's pokemon are dark, and another could answer yes and no. Yes, all her fusion pokemon are enhanced in their fighting abilities, and have their attacks morfed to a dark attack.
No, all of her pokemon are just like any other pokemon in emotional capacity, and could feel love just as any other could.
One thing Salva found also, was this: When she transfered her Umbreon, a dark pokemon by nature, lacking most of the emotional capacity of a normal pokemon, it changed it to a fusion, but a more powerful version than the others. It gave it the ability to think like others, and love, but gave it immense power, unlike any other. Some who have experienced her pokemon in battle say they can be likened to legendary, with their fusion title.
