Hi again, Darkangel. Well, take a double Scorpio: this person could have Sun and Moon in this sign but maybe not so much going on with Pluto and Scorpio themes anywhere else in the Chart... The Scorpio traits would be pronounced, but the person wouldn't necessarily be classified as a "Plutonian" without any major Pluto aspect, or 8th House placements, or stuff going on with the 8th House ruler(s), etc. etc. On the other hand somebody might not be a Scorpio and then having Pluto aspecting the majority of the Chart, or in an angular position, significant 8th House placements, a 8th House stellium, 8th House rulers in a prominent position, etc., the Plutonian energy and Plutonian themes in the life of this individual would take center stage.
So in your case, I think a Sun/Pluto conjuntion in an angular House, Scorpio Midheaven and a further contact between Pluto and Moon would classify you as fairly Plutonian even though there's no textbook definition for this. Do you happen to have Planets in the 8th House? What is your 8th House ruler doing in your Chart?
