>>16489547The Pokemon Universe has physical beings to act as immanent conduits for laws of nature and physics - hard to draw definite parallels between living beings we know and these ficticious creatures.
For all we know, all Pokemon may as well be interlinked on some level that remains out of perception - entire living network, ever fertile, with existent Pokemon as observable manifestations of it - hence compatibile Pokemon only need some affection towards each other to trigger this hidden fertility of entire network.
And Poof! Before you know it, your Trevenant and Magcargo have been blessed with an offspring.
