Which of Ash's Oak'd Pokemon do you never see him using again?

[Solana]

I'll say Muk and Cyndaquil. Has Muk battled even five times?

Cyndaquil is just so weak and Ash prefers Charizard so he has no use for Cyndaquil.

 

[Cybersai]

Ash used Muk against Gary in the Johto league, and that was the last time he used it. Muk is pretty decent as a battler, its just underused.

 

[DashingFox]

I think Muk has potential but Ash has to use it more in order to prove that. I mean, gosh has that thing ever gotten a win besides the one off the hyper Bellsprout back at the Indigo League?

 

[Nomura]

To put it simply, nothing is gauranteed. But, the pokemon we can be sure to see him use again are as followed.

-Charizard
-Sceptile
-Bulbasaur
-Snoralax
-Squirtle
-Heracross
-Tauros
-Donphan
-Glalie

In terms of his other johto pokemon though, I think we have a better chance of seeing Lapras or Primeape again than that.

 

[Kairyu]

Well the most certain choice for who he will actually bring back is - ofc - Charizard. He always returns since the writers love him. (A whole movie dedicated to him, anyone?)

Poke's he will not bring back: Totodile, Cyndaquil, Bayleef. Noctowl have a shot since it has foresight, so Ash will maybe bring it back when he meets some Ghost types.

 

[Mayiscool]

Ash should have gaveing May his Noctowl, it whould have been great for the Contests since it's a shiny one.

Thow we probely never see him use Noctowl agian.
