>>45455170Except that Dragapult doesnt have two different formes based on how many pokemon it has. From a technical standpoint those two "Dreepy" are part of the Pokemon, somewhat similar to the baby kangaskhan or Exeggcute and not individual Pokemon (even though individual Dreepy exist). This means that you cant find a Dragapult without the other 2 Pokemon being part of it.
Necrozma and Kyurem can "fuse" with other individual Pokemon, so it KINDA makes sense to call those new formes that include other Pokemon, but Calyrex is just...there.
So having the two horses share the Pokeball with Calyrex, simply because its riding them, doesnt make sense when they usually take an individal Pokeball
