Due to the possible return of Gliscor

[Ishida]

Well with Gliscor possibly reappearing why do you think the writers decided to bring the Bat Scorpion back but not Ambipom or any other pokemon(Pidgeot,Primeape). Some people say it's because Gliscor lost to Paul and had something to prove Ambipom lost to Kenny and Zoey as an Aipom. Some people say Ambipom didn't return because it took up a new interest but really why do you think the writers choose to bring Gliscor back?(Maybe they had enough of Scotts complaining)

But, think of it, in replace with who Pokémon who?? Who would replace gliscor, in place of..

Ambipom is Dawn's, not Ash's.

It won't return, but either way since Dawn's leaving it doesn't matter.

No matter how much we want it to return, its highly unlikely that it will

Gliscor was brought back because of the possibility that its skills have improved while in training.
