Which of Ash's Pokemon should evolve, and should not

[KrspaceT]

The question is a simple one. Ash has many unevolved Pokemon. Some fans could argue they would be more badass if they evolved. Others are badass for not evolving.

The question becomes, which ones are which?

Which of Ash's NFE'd Pokemon should evolve, and which shouldn't.

We already have a thread for this and other characters as well: Pokémon Evolution/Capture/Release Thread

 

[Hidden Mew]

As already pointed out, there is a thread for captures/releases/evolutions, so I will go ahead and close this thread.
