>>40734286they have a different reason to exist in the universe, albeit it's not precised what they are exactly. while they're supposed to be mimics to us, in the world itself, they're either unknown entities that camouflage themselves as pokeballs to then self-destruct in the face of the trainer trying to pick them up (literally a mimic), or an unknown entities that was discovered when pokeballs were made (and that's where we first saw them), that there are some connections to them, that the rumor is that they're just pokeballs exposed to high energy and that it was discovered that its components aren't natural. while the pokedex isn't that reliable and we have the proof here since we have different origins, discarding the voltorb line as purely random is just plain wrong.
>The Electrode line doesn't have this excuse, as they aren't inherently artificialcrystal entry. components imply that it's not a creature and "not found in nature" is a strong implication that they're probably man-made. we know that they aren't natural though.
