I'm just asking if there is a pokemon white action replay character modifier if there is one, can somebody tell me?
Not sure there is, what sort of character modifier are you looking for anyway? One can always use POKEGEN or PIKAEDIT to modify most of anything stored in your save file. But those aren't AR codes. If you can make do with that as alternative, then just Google it.
The character modifier i'm referring to is temporarily changing your overworld sprite to an npc overworld sprite, they had a code like this in DPPtHGSS. Also, I can't find it on google which is y i'm asking.
