Fight Club!
[ Ingo and Emmet's pearl presences are both here, focused enough for a fairly clear visual. Ingo's speaking aloud as well, because that is how he tends to use the pearls; those in the Oran Berry quarters might be able to hear his voice echoing down a tunnel. ]
I am Ingo, and this is my brother Emmet! We would like to issue all of you a challenge!
[ They....are they posing? They're posing. Somehow over a psychic network. ]
Doubles format - two versus two! The battle shall last until both members of a team have tapped out! Attempts to cause actual serious harm are forbidden! Will you be able to overcome our teamwork?
Emmet, do you have anything to add?
I am Emmet! I like combinations of two Pokemon. Let's have fun with a serious battle, okay? Your combination against ours!
