do you always let your pokemon evolve?

[Bing]

Ehhh I should probably mention that my hail team is a borderline team.  I'm not sure if his evolved form is borderline.

[Mr. Fox]

no, i think its ou.

The most interesting Trainer in the world:
"I don't always evolve my Pokemon, but when I do, they become stronger!"

[Hinagiku]

I almost always let them evolve, often for my Pokedex, but also because the stats are higher. Even if I don't like an evolution at first, I usually learn to love it (such is my case with Walrein and Wailord).
I use my Eevees' personalities to decide their evolution, in those specific cases. The only Pokemon I don't really ever evolve is Dragonair, because I don't care for Dragonite all that much. If I get a second Dragonair, I might choose to have it evolve. But not the one I actually use in battles.

[Bing]

For this whole topic, it honestly depends... On if they can only learn a move I want in an earlier stage.  If not I always evolve them.

Most pokémon need evolution in order to get stronger stats, however there are some  that not neccesarily get stronger by simply evolving like scyther or pikachu, or another few. As for scyther and Pikachu it's mainly the speed diffrence.

Usually I let them evolve for the sake of being strong enough to beat the game. However, there were times where I had a Charmander around level 83 because I liked him that way. But theres no way you can keep a caterpie the way it is and keep it viable to fight with just Tackle and Stringshot. Unless you go for the batonpass method to support it.

I don't know where you're getting your information from, but Pikachu has terrible stats compared to Raichu. He goes from 300 total base stats to 475 total. But yeah, pokemon like Scyther don't need to evolve to keep up. With pokemon who evolve with stones, you might want to make sure you have all the moves you want, as most of them don't learn any more by level up.

Indeed, only thing that Pikachu has more than Raichu is possible Sp.Atk obtained from the Light Ball, but then... Pikachu is more of a physical pokemon...

[Burning Roses]

i sorry to tell you this jerry hun, it double atk and Sp atk.

[Jerry]

Yes, if you look at the previous versions, it raised its sp. atk only:

I never bothered to check it again after DPPt because I didn't play HGSS or BW with lightball.

sry but as someone who loves raichu and hates pikachu .... pikachu is much better

[TheSolx]

How can you hate Raichu?

In my personal opinion, my "fan-view of Pikachu were ruined after a few seasons with a guy with the weird hat and the weird voice that obviously can't age. (Yes, I'm talking about Ash)
