Scorpio is usually compatible with Taurus, because the signs are polar opposites and balance each other. The Water of Scorpio and the Earth of Taurus mix well. However, both signs are fixed, which means that in a disagreement neither will give in to the other. Scorpios can be compatible with other Scorpios as long as each person understands the other's intensity and passions. Pisces and Cancer, the other two Water signs, may be too weak for Scorpio's intensity, unless a comparison of natal charts indicates otherwise.

Fire signs may blend well with Scorpio, depending on their charts. If a Scorpio is emotionally solid, a Leo may be a good match. Scorpio loves Leo's sunny nature, and is drawn to it. If Scorpio doesn't pull Leo down with him, this can work okay. Sagittarius, especially if Scorpio is near the cusp of Sagittarius, can be the same — but ditto with the “bringing her down with the house.” If the two can respect each other and find a good balance, this can work. Aries and Scorpio, however, will find that the emotional gap is probably too much of a chasm to cross.
