What Deoxys form wasn't available before Emerald?

Question

Deoxys had had only one form before FRLG, and only had three forms before Emerald.

I think all Deoxys traded to Emerald become speed form, so it has 3 forms that are not available in Emerald.

Answer 1

In Pokémon Emerald, Deoxys is battled and caught in Normal form. However, once caught, It reverts to Speed form, and cannot be changed without trading. So to answer your question, Normal, Attack, and Defense forms are unavailable in Pokémon Emerald. If you want the other forms you need to trade with FRLG. Hope this helps!
