Play on intense mode also if you put certain stickers on your characters you can make trophy stands appear more as well.
I think intense mode
Only in the adventure mode and enimies randomly drop them
After having everyone join your team in the Subspace Emissinary go into all-star mode as Sonic and you you will find the Shadow Trophy after you beat Kirby characters.
It appears randomly it appears more often the harder the mode you put it on also you can give certain stickers to your characters to make trophy stands appear more often.
Yes she does
TT stands for "Tourist Trophy" and NOT "Twin Turbo."
No they appear randomly
At the end of the game, new Pokemon appear in the trophy garden. one hint. max repels and a pokeradar.
You can't you must use the trophy stand item on rayquaza at the lake to get it's trophy.
You need to weaken Rayquaza as best as you can then wait for a trophy stand to appear. This can only be done in Sub-Space Emissary. Or you can get it by shooting your coins at the trophy in Coin Launcher Mode.
It will appear in the Trophy Garden which I think is just under Hearthorme Town.
He's not a playable character and I'm almost positive he doesn't appear as an Assist Trophy.
