Metalizard said:your post is fail... So, it is an ariados evo just because spinarak changes the main color when evolves? It seems it is you who didn't read my post.
And old pokémon never evolve to new pokémon using items that already exist when the evo is made, like thunderstone...
First of all, you happen to appear to actually of just read the first line or just look at the images, I'm not going to argue you with; even if it appears you so dearly desire it.
And my post was mostly pointing out every single similarity between them; which happens to be quite a lot, their colour is unimportant.
The thunderstone thing was a simple speculation, if it is absurd or not doesn't trouble me; nor does if it evolves from Ariados or not. I simply was posting the similarities and my opinion on the matter; which appears to trouble you.
