Since there is no room for two kings in one kingdom, this combination is not an ideal match. The fiery independence and vital spirit in Aries that Scorpio initially liked can lose its charm soon. Because both are natural, born leaders and only one of them can lead. Scorpio may also be intimidated by Aries` leadership tendencies, which may lead to a considerable amount of resentment. With Mars dominating both signs, it makes for very positive temperaments unless one of them has benign natal planetary aspects. Under such circumstances, they may prove to be an ideal match. However this is rare. Scorpio may adore Aries from a sexual standpoint. He can satisfy her deepest desires and their sexual magnetism for each other can transcend the barrier of age. Even in the old age you would find Aries-Scorpio having as much passion as they had in their youth. However, their more mundane interests would be constantly at odds. While Pluto rules Scorpio`s mind, making him shrewd and sceptical, Aries has a carefree, uncomplicated and impulsive attitude. This difference in their mental outlook can either make or break this relationship. The harmony between the two also depends on the sun-moon aspects of their horoscopes.
