I can add my observations of those who have heavy Scorpion energy in their charts i.e. stelliums. I think stelliums help to better grasp the "typical" pattern of a sign, in the sense of prototypical rather than stereotypical. I have had a positive experience with the people of this sign, probably due to the fact that it is my 11th house cusp. Nevertheless, I don't think that will cloud my judgment on these individuals.
I am making observations based on:
Person 1 Male - Scorpio stellium (Sun, Mars, Pluto, Mercury) 1991
Person 2 Female- Scorpio stellium (Sun, Mercury Rx, Pluto, Mars) 1993
Person 3 Female - Scorpio stellium (Venus, Mercury, Sun, Mars) 1929
Person 4 Male - Scorpio stellium (Mercury, Venus Rx, Sun, Jupiter, Pluto) 1994
Person 5 Female - Scorpio stellium (Mercury, Venus Rx, Sun, Jupiter, Pluto) 1994
Person 6 Male - Scorpio stellium (possibly Moon, Mercury, Jupiter, Venus, Pluto) 1994
Person 7 Male - Scorpio stellium (Mercury, Venus, Jupiter, Pluto) 1994
All the 1994 births also had the NN in Scorpio.
The majority of what I say will be based on those with the Sun in their stelliums. I added the last two because of a sort of "division" I see in them. I'll elaborate more in a while. Also notice that the sun isn't in these last two stelliums.
The "energy" of this group I would describe broadly as a low humming engine; they are generally quiet but it is a quiet that is "pregnant". There is something muted and watchful about them.
They are long-term oriented and deeply committed. Not adaptable but this is no surprise as the sign is fixed. As a result of their lack of flexibility I see two traits manifest - they can be deeply affected by phenomena which stays with them for many years or the rest of their lives - in the case of the one born in 1929, upon losing her child in a miscarriage and then her husband, she gave up on life and became the famous "grey lizard" iteration of the Scorpio energy. The other is a territoriality that I think all the fixed signs show in different ways. Leo and Scorpio can be "fierce" although Scorpio uses more innuendo and implication when showing force. All of the solar Scorpio display immovability comfortably - they are more defensive than offensive. They do seem to have a greater ability to scheme and to be patient, which is great especially when they are young since their peer group may not have the same level of control on their impulses.
I am currently most in contact with Male 1 and female 2 and in my current environment, I'd say that they are among those few that I would describe as having "depth". What I mean is, they display a level of self-awareness, breadth of understanding in regard to their actions, responsibility and ownership of the decisions they make, have taken the time to know what motivates them and they are devoted to those that they love in a way that can almost be construed as self-sacrificing wrapped up with a willingness to remain steadfast to their convictions. They will work assiduously to the point of exhaustion for the ones that they hold most dear. They are loyal people and aren't easily impressed by a glamorous display.
Some in the group have a provocative reputation; attached to male 1 is an air of "implied violence" coupled with no desire to feign or fake to please anybody, female 2 is rumored to have slept with her boss for her position (conveniently nobody sees this person going above and beyond the call of duty even to the point of covering the asses of her lazier co-workers), female 3 was known to be very quick to violence and ruthless in her more youthful days, Male 4 lives a musician lifestyle with all the drugs, parties and women that that entails, and female 5 is seen as confrontational, verbally threatening, and sexually provocative.
This group is a practical set of people - their aims and drives are mostly grounded in the material world and success in that sphere, which is not to say that these persons lack spirituality or deeper values. One person of the group can be confirmed to be deeply spiritual with magical interests (although not as a practitioner) but I think that can partly be explained by the era she grew up in. If Scorpio contributes to mysticism or a focus on the occult, these individuals do not display that trait. It could also be a deeply private affair which is not out of the picture, but then I've spoken to some of these people enough to know that a spiritual conception of the world is not fundamental to their way of life.
They also tend to be soft-spoken and male 1 is even something of a whisperer. Female 5 is probably only solar Scorpio that breaks the trend in this group but this could be explained by her identifying more with her Aries Moon as well as a possibly more outgoing/boisterous ascendant.
Of the last two individuals, I still sense that many of the traits just mentioned are present, however both have a more lighter, polite , playful and socially conforming that belies the deeper locomotive energy that their Scorpio stellium might give them. This division I sense in them I see as making them liable to be hypocrites or deliberately misdirecting even though it might not be as skillfully hidden as the solar Scorpio. They seem not to own their "darkness" and even have an issue with it, which may lead them into quite a bit of moral dilemmas. What they share in common is that both are very physically oriented/strong relative to their body types and both have jobs related to the sea.
I didn't bother to use the word intense even once in my descriptions of these persons since its a word that is so imprecise and seems to be dependent on someone's subjective threshold for "intense" behaviour.
