That makes sense. It also gives writers/artists free rein to change her armor's appearance at will with no explanation.It seems Armor can create her outer shell to be any shape she wants, so maybe she likes horns...or maybe that was her feelings as she molested Wolverine before she threw him.
It looked like the only people having any fun in those scenes were Logan and that tranny posing as Storm. The rest were probably hoping there were no cameras nearby to record them.On a side note, you see how ashamed Armor seems in that picture after she threw him.
