Alright, im back. Here's my update, and just like always I have 3 lies in here.
Another Fire Emblem level will be in.
Mewtwo will be returning.
Leafeon, Vaporeon, and Jolteon will be pokeball pokemon.
There will be no rival P.T. in the game. (C'mon Blaziken, Turtwig, and Croconaw I think it was no, if anything it would be Blastoise, Charmeleon, and Bulbasaur, maybe or maybe not, but I do know Blastoise would be in the there.
Rayquaza will not be the only Pokemon boss in Subspace Emissary.
The third 3rd party character is from Capcom.
There will be a level in here that will have SNES graphics. (I have no idea what it's from, but that's how it was described to me.)
After you get all the cds, you can supposedly upload your own music via memory stick.
Twilight Fossil- Stallord, and Twilight Igniter- Fyrus are bosses in Subspace Emissary.
Monty Mole, and Professor E. Gadd are assist trophies.
Big Goron's Sword, and Poison Mushroom are items.
I don't know the next time I will update you guys with info, but I will update again.
