The First Pokeball

"When an apricorn's outer shell is taken out, and the fruit underneath is hollowed out, then it can help carry more than two Pokemon at a time." Kurt explained to his new apprentice.
"How?" He asked, disbelieving.
"Apricorns are a delicious treat for Pokemon. However, it has developed a defence mechanism to counter this. Apricorns have developed a plasma that can envelope a creature and seal it inside the inner shell when the outer shell is broken. If the apricorn too weak, or the Pokemon too strong, the apricorn will break."
"What happens if the Pokemon gets sealed inside?" The apprentice asked.
"It is held in biostatus until the fruit rots. We can, if we are careful, pull out the unnessacery parts, and use it to carry our allies."
"M'kaythanksbye!" The apprentice grabbed the apricorn shell out of Kurt's hand and chucked it at his Pidgey partner. She was sucked inside and was "caught". The boy ran out the door. Kurt decided the kid just wanted his new invention, as usual.
A few minutes later, he sold his invention to some visiting Silph Co. agents.

A few months later, one of the lead scientists working on the pokeball project managed to get apricorn plasma inside a synthetic shell. He brought it to the president, who eagerly asked about it.
"What happens if a non-Pokemon is sucked inside? " he asked the scientist.
"It will correct the mistake. I have added a safety lock so that most humans won't be sucked inside. It will stun them, though."
"Does it work?" The president pressed. However, the man would give a direct answer. "It's safe," was all that he would say.
Eventually the president gave in and marketed them. They became widely popular, and Silph products shot out the roof. New kinds emerged, and some could only be obtained via traditional apricorn workers. New laws were made, making Trainers carry only six at a time, and you could not harm a Pokemon by bludgeoning them with the tool. Nobody questioned how the heck they defied physics, logic, and most other forms of science, which may have been for the better.
True was an experienced Trainer, finishing her Freshman year at Trainer school. Her Quilava sat just drawing on her note pad using her Charcoal.
"Class, it's time for Battle lessons!" The teacher said. "Go to the field out side and find a partner."
True found her friend Cassia and thought up new tactics, strategies, and move combos, which led to a battle to test them out. They started a competition to see who could throw the best flair in a pokeball and still hit its target.
"Man..." True whined, watching Cassia throw the pokeball with a flick to cause it to corkscrew and hit the target perfectly. "How do you DO that?!"
"It's called a homing device. If you're careful, you can get it to center on anything. Like this." Cassia pooped the sphere into the air where it soared for a ew seconds, then made a "Clonk" on True's head. Amazingly, the stunner was ineffective and True got sucked inside. "Oooohhhh, craaaapppp..."Cassia said.
