Speaking of Digimon: There was a day where I dreamed there was a new Digimon season where one of the Digidestined had two fathers. Makes me wish this actually happened. I wonder how they'd handle this?
English dub would probably make them "friends" or "brothers" or something. I would imagine the Japanese version would probably keep it subtle or avoid making it all that relevant.
Just want to add that Most Pokemon didn't have very impressive feats or actually shown using their abilities as described by the Pokedex and we all know how accurate Pokedex are. If we ignore all these Pokedex "feats" It's far more conceivable that Digimon would win. I mean a 10 year old kid could catch "God", although you could argue that it wasn't "canon".
Counting the Pokedex as all truth should tip it in Pokemon's favor, if we consider that all the creation trio is in fact, capable of doing what the myths said they can, otherwise, Digimon wins in a landslide.
