Someone asked "what would be a good legendary trio for this 6th generation" and then...
Three Light Type Pokemon
Who are you? Idgaf cause I love you already!
Well I think my theory is right, every even numbered generation has evos and pre-evos of
Previous Pokemon . Generation 2 brought the likes of Blissey, Scizor, Elekid, etc.
3rd generation (altho it brought Azurill and Wynaut) really had mainly new Pokemon unrelated to previous ones.
4th generation had so many evos and pre-evos to previous like Bonsly, Weavile, Electivire, Yanmega, etc.
5th generation had NO RELATION to any of the previous Pokemon at all.
So here we are at 6th and I believe this generation will have many relatives of previous ones.
I don't believe however that there will be evolutions to previous single stage or final stage pokemon because that would throw off the eviolite factor. Game Freak makes sure there is a reasonable explanation for how they evolve or how they factor in evolution that doesn't completely change from one generation to the next.
The most they will do is pre-evo a lot of previous Pokemon or branch em to other evolutions like they did Slowpoke and Poliwhirl to still make the eviolite factor valid from one generation to the next. Hopefully Gamefreak makes better bulky pre-evos of Pokemon to make eviolite monstrous.
Oh yeah and Light/Pure types ftw! Lol
