This is definitely not the weakest poke'mon from Ash. This is his strongest poke'mon ever. They have a big bond even when they're far away from each other. Go Ash and Greninja!
Greninja isn't ash's only good water type or anything. BUT, he's the only ace in the whole-styled water type that he has.

Buizel, known in Japan as Buoysel, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. He's always focused and serious. He's just a really cool Pokemon!

I think I heard he is tied with 2 others for Ash's worst pokemon.
Lapras is one of the best water type.
Only used for transportation
It should at least be in the top 3
5 Kingler
Kingler, known in Japan as Kingler, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. Underused since the Indigo League. Poor Kingler. And he battled so well there.
6 Oshawott
Oshawott, known in Japan as Mijumaru, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. Little brat. He's adorable though, and can do a lot in a fight. (Oh, and do not get between him and Meloetta! )
Honestly he is just cute
7 Totodile
Totodile, known in Japan as Waninoko, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. I've always found him very annoying. But he did help Ash win several battles.
Cutest pokemon ever
8 Corphish
Love his quick-tempered and lively personality. He's a pretty tough battler too.
9 Palpitoad
I'd like to see him return some day. He didn't get much attention in Unova.
10 Froakie
Froakie, known in Japan as Keromatsu, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. He's too adorable to not be mentioned on this list! He was so ready to go with Ash, he practically caught himself, jumping into the Pokeball. Ash didn't catch Froakie, Froakie let himself be caught.
Froakie is the best pokemon to choose as a starter
The Contenders
