I have the set, only Lightning and Ice have thornax launchers in their mouths. One of the balls is red so it's kind of strange. Plus the set only came with one zamor/ball thing, and it was lime green and kind of translucent in a way.
EDIT: Oh wow, I looked at the picture again and it shows Fire with the thornax launcher in it's mouth instead of Ice! That explains the red ball, but this is definitely the prototype for the set too.
