Pluto represents the transformation of instinctive energies into conscious resources. It can be associated with the creation of the nuclear bomb and the development of psychoanalysis, as well as with the underworld and the Mafia. It is also associated with the power complex and the failure complex.

In the Greek tradition, Mars or Aries was the god of war. Although it also symbolizes the elder brother in the cosmic family, it is more likely to be associated with declared enemies or adversaries. Mars morphology is typically virile, angular, and athletic and corresponds to aggressive, domineering, masculine behavior. Likewise, Mars is usually associated with rage, its resultant brutality, and male destructiveness and domination. Psychologically, Mars figures in any situation of conflict, opposition, and confrontation. Martian symbolism intervenes to separate, oppose, and decide and corresponds to duels, war, and any situation in real life which involves confronting an obstacle. Individuals who are greatly influenced by Mars are typically direct and straightforward—either unabashedly extroverted or furiously introverted. They are extremely active and extremely emotive. Their purpose in life seems to be inextricably mingled with a combat against an unacceptable situation, a challenge which they either issue or are forced to accept.
