Good question, for this answer better you check the birth chart of India’s PM Shree Narendra Modiji..!

He has debilitated Moon in the first house in scorpio while he has placement of Mars (Lagnesh) in the lagna itself. So debilitated Moon is placed with lord of dispositor sign Scorpio. Which causes immense Neecha Bhanga Rajyog as well as Kendradhipathi Bhagyadhipathi Rajyog..!

Currently his Moon mahadasha is ongoing till this year end. and then he will have Mars Mahadasha which is his lagnesh so we are expecting even huge from him in the coming years..!

So coming back to your question, see you are asking what types of Neechbhanga does Scorpio has..! See, here there is confusion in your question, which is not clear whether you are asking for Neechbhanga as Scorpio ascendants or as Scorpio sign..! Neechbhanga may happen for every sign except for Taurus, Gemini, Leo, Sagittarius & Aquarius signs because these signs do not have debilitation of any planet.

For Scorpio as a sign, neechbhanga rajyog may happen for Moon in below mentioned conditions;
(1) Scorpio lord Mars is placed in Scorpio
(2) Mars is exalted in Capricorn
(3) Venus is exalted in Pisces
(4) Scorpio lord Mars is placed in Kendra from Moon so Mars should be either in Aquarius, Taurus, Leo or in Scorpio.
(5) Scorpio lord Mars is placed in Cancer sign so Moon & Mars will have exchange relationship
(6) Debilitated Moon and Mars is having mutual aspects with each other so here Mars must be placed in Taurus so Mars & Moon both will have their 7th aspects on each other.
(7) Moon is exalted in Taurus sign in Navamsa (D-9) chart.

So these are how Scorpio sign may have Neechabhanga Rajyog..!
