Wasn't there a size comparison with a human vs the Aliens
queen vs AVP
queen? I seem to remember the Aliens
queen not being too
much larger than a regular xeno.
EDIT: Never mind, she's pretty huge, though still smaller than the AVP queen...
As for action figure scale, the Xeno warrior towers over Dutch, who in turn would tower over Ripley, so the queen may not be as large as we may think. The egg sacs would make this a huge figure, but without the egg sacs I can't see her being ridiculously huge.
