I forget which series did it but there was one where the humans and Digimon merged for a temporary evolution, I want to say it was Tamers or maybe Savers. I was thinking my character instead of it being temporary it was somehow accidentally made permanent.

So my Tamermon (for the lack of a better word right now) is now stuck at like the Adult or Perfect level can't go back to being a Child or Baby.

I was also thinking my Tamermon back when he was still human had two Digimon like Wallace did in Adventures. Tamermon is only merged with one of them.

I know the Japanese terms for most everything, I don't know the [s]butchered[/s] American dub names for anything except evolution is called Digivolution or something like that.
