Need artist Id.
Character ID needed - Two girls with helmet/hat on at the table, the standing girl behind Ro, the girl feeding FNC, and possibly, the head Sophie is holding.

Just realized there was 2 ROs

The girl feeding FNC is FN-49

Also the girl standing behind Ro at the extreme left side is MP7, the bear pouch is a dead giveaway.

Which I think just leaves Sophie's trophy head, along with three heads and an upper torso in the guro pile.

The head that SOP is holding likely belongs to Destroyer . If you look at the head's bangs you can see that they cross over the same way that Destroyer's does.

The only one not injured, ironically, was Ribeyrolles.

Actually, the torso in the corpse pile looks like Ribeyrolles, the head with both eyes next to it seems to be Vector, and the stray foot with mary janes is Sten mk2. Not sure of the waist without knowing if the legs go with it. Lastly , I agree with the craddled head being Destroyer
