I was thinking, maybe not even that. Maybe there could be some 2 headed thing that could be both fire and water without actually conflicting...or something.
So, aditional evolution methods? We've had them in the past.
1st gen basis of evolution
2nd gen trading with an item, not sure if that was new, but I think so. At any rate day and night happiness evolutions were new for sure, and actually regular happiness evolutions might have been new too since I'm not even sure happiness existed in first gen.
3rd gen: erm. Maybe my theory is broken here. I actually don't think there was a new evolution method.
Correct me if I'm wrong.
Anyway... Sinnoh.
4th gen: Area based evolutions, and also evolutions based on team members (mantyke's evolution.
5th gen: We have the trade with a spesific other Pokémon method.
I'm not sure if there was any other new evo methods introduced, I've forgotten now.
So, if any, what kind of new evolution methods do you think may be added?
Something that would be really really annoying would be regional evolution. For the Pokémon to evolve, it has to be traded with a person from another country. This takes away the ability to trade with yourself. And it just seems like the annoying thing game freak would do. As annoying as this would be, I am actually not apposed to it. It would be interesting to have to work that hard for an evolution. I'm not saying this for tons of Pokémon, but maybe just for 1 spesific Pokémon, or perhaps 2 at most.
