Mars/Neptune combines the action, athleticism, and drive of Mars with the water, idealization, image, and spirituality of Neptune:
The Mars/Neptune combination often shows up as the idealized (Neptune) athlete (Mars). Examples of this can be seen in the chart and life of soccer star Cristiano Ronaldo, and in the chart and life of basketball star Michael Jordan.
The Mars/Neptune combination creates a dynamic in which dreams, beliefs and faith (Neptune) are a impetus for action (Mars). Singer Diana Ross demonstrates this dynamic of the Mars/Neptune combination in her chart in the following quotes: “You can't just sit there and wait for people to give you that golden dream. You've got to get out there and make it happen for yourself.” “If I have someone who believes in me, I can move mountains.” “You know, you do need mentors, but in the end, you really just need to believe in yourself.”
The Mars/Neptune combination can show up as action or battle (Mars) spurred on by image (Neptune). Singer Rod Stewart exemplifies this dynamic in his chart with the following quote: “Half the battle is selling music, not singing it. It's the image, not what you sing.”
When one is born with Mars and Neptune together we see Mar’s action-oriented tendency toward bravery and conflict combined with the water-like and spiritual qualities of Neptune. In the world of martial arts this combination can be commonly seen; it lends a sort of flowing ballet-like beauty to the art of fighting. Quentin Tarantino, director of the “Kill Bill” volume, his famous homage to martial arts movies, was born with Mars and Neptune combined, as was Uma Thurman, the lead heroine assassin in the film series, and her co-star Vivika A. Fox. Multiple members of the hip hop group Wu-Tang Clan were born with Mars and Neptune in combination. Their allegiance to martial arts is a consistent theme strung throughout their songs. A champion of the UFC (Ultimate Fighting Championship), Khabib Nurmagomedov, was born with Mars and Neptune combined. This combination is not without its challenges. The watery infinitude associated with Neptune can allow the pugnacious quality of Mars to bleed into inappropriate areas of life, causing problems. In the case of Khabib Nurmagomedov we saw this when he beat his opponent in his championship match and then leapt into the crowd and started a fight, causing a riot to break out: https://www.youtube.com/watch?v=duuH3s1blzI A way to address this “leaky” (Neptune) aggression (Mars) is by integrating the spiritual (Neptune) side of Mars. Aikido is revered as perhaps one of the most flowing and spiritually-based of the martial arts traditions. It’s founder, Morihei Ueshiba, was born when Mars and Neptune were together: https://www.youtube.com/watch?v=tZcDc1ZYEgw&t=83s
