The alternate emotional center was pretty quiet...
"Excellent. First, I'm going to give an overview of the presentation and the subject, which I am most of the way through doing. Next, I will go over the known and unknown members of the Bones, and their powers, strengths, and weaknesses as they are known. After that, I will explain other reasons to be concerned about the Bones. Finally, I will bring up some plans of action to deal with this threat."
Argonaut shifts his arm. On the screen comes a picture of a thin man in a black body suit that has a skeleton pattern on it. It almost looks like a cheap Halloween costume.
"This is Skull, the leader of the Bones. Don't judge by his cover--he possesses a power suited to a horror movie. Skull controls skeletons. His application of this power are controlling the movement of people and corpses, and animating a number of skeletons with simple hinges or springs added to the joints as cheap soldiers. These skeletons are incredibly weak, but difficult to permanently damage them. You must disconnect the joints, firmly enough to prevent the bones from coming back together--or break the bones, which may have once been easier. I will get to this in a moment. As to the control, again until recently only crude physical control was possible. Skull has been recorded as forcing people to strip flesh from their bones, leap off of tall buildings, or even shoot themselves in the head, but keep three things in mind. One: He only controls bones. This makes his movements of you crude at best, and incapable of using many distinctive patterns. Skull cannot control speech, nor can he move your eyes, ears, or other fleshy body parts, nor can he use any powers not constantly active one may possess, except for a few simpler ones such as a few super-strong or -fast individuals, notably Felis Nocht. Onto his psychological profile. Skull is believed to be a megalomaniac to some degree, and is known to have a long view that may well help him achieve his goals. Moreover, he constantly strives to gain more power...and more powers. By hook or crook, or way or pass, he has been getting every parahuman not already associated with some team and several who are to join the Bones. Recently, he has been successful often as not, with a sudden influx of new capes. One has to wonder why...but this is for later."
A pause. (Mostly to help break up what would otherwise be a ginormous Wall of Text, but it also gives PCs a chance to comment on each section.)
