The energies of Pluto and Mercury 

Both Pluto and Mercury are pivotal planets in a natal chart and synastry. Pluto, the planet of transformation and the underworld, and Mercury, the messenger of the gods governing communication and intellect, bring vital energies in all their placements. 

Pluto, also known as the God of the Underworld, speaks of our subconscious and intuitive energy. It brings transformation, radical changes, and the power of rebirth. It is a planet that works with our shadow selves, bringing to the surface profound fears, traumas, and thoughts. But Pluto’s goal is to help us overcome these struggles and grow into a better version of ourselves. It gets rid of what no longer serves us and makes room for even better experiences and relationships in our lives. As the ruler of Scorpio, Pluto is in touch with our dark secrets, mysteries, and past traumas. As Pluto tries to unlock your destiny, it is essential to consider that the path it opens is never easy. 

By using Pluto’s energy we embrace our healing and allow ourselves to overcome our darker side. This is a planet of truth and it aims to bring to the light everything that lays in the hidden corners of our being. 

On the other hand, Mercury, the messenger of the Gods, rules over our intellect, communication, and the way we process information. Mercury governs logic and rationality, as well as how we connect with others through language. Its energy is quick and impacts us in a more direct manner, as this is one of the personal planets in a chart. Mercury is the rule of Gemini, a profound psychological sign, just like Virgo. We look at Mercury to see how we interact with others and exchange information, verbally or in writing. Mercury in Aries is more direct and rational than the dreamy and sometimes volatile Mercury in Libra. This planet also influences travel, online communications, and technology. We look at Mercury in a birth chart to discover the native’s logical, rational, and analytical side.

Challenges of Pluto square Mercury synastry 

While Pluto square Mercury is a challenging aspect, it is not one that dooms a relationship. It might not be one of the harmonious, flowing aspects, but it pushes both partners to understand themselves at a very profound level. 

Power Struggles

Communication Breakdowns

Obsessive Behavior 

The obsessive behavior in Pluto square Mercury aspect is coming more from Pluto’s energy. Like in all Mercury-Pluto aspects, Mercury tries to rationalize Pluto’s energy.

Potential of Manipulation 

Since Pluto is all about digging beneath the surface, there is a fear of manipulation and deceit lingering in this relationship. The Pluto person might fear that their partner is trying to manipulate them. Also, Mercury sees their partner’s trying to uncover the truth rather stressful and unreasonable. 


Both partners could be stubborn to a certain degree when Mercury and Pluto form a square in their synastry. Other aspects of the synastry chart could accentuate or lighten up this challenge.
