oh another thing that just came to mind.....
1.which pokes will we see in the loading screens
2.or in the training section as a dummy if that will be there.
3.might there be a shop of some sorts
write your guesses below
I think:
1. first in evolution-line pokes of the fighters + pikachu if raichu will be a candidate (sad pichu)
2. wobbuffet, snorlax, machamp, a substitute
3. depends if you can upgrade/buy pokes/moves
