Random Least Compatible Zodiac Signs (12 items)

(#5) Leo (July 23 - August 22)

Least Compatible Signs: Taurus, Scorpio
Opposite Sign: Aquarius
Leos are least compatible with Taurus and Scorpio. With Taurus, there could be a battle of wills - both signs are headstrong and quite used to getting exactly what they want. Scorpio might be a bit too strong-willed for Leo (in this way, the two signs are actually TOO similar).
Leo's opposite sign, Aquarius, isn't always a good match, because Leo might think Aquarius is too detached and airy.
(#2) Taurus (April 20 - May 20)

Least Compatible Signs: Leo, Aquarius
Opposite Sign: Scorpio
Those born under the sign of Taurus are said to be least compatible with Leo and Aquarius, with the opposite sign being Scorpio. It's not entirely surprising, though, that Taurus might be drawn to Scorpio's magnetism -- but the match isn't always harmonious. Taurus might have some trouble adjusting to Scorpio's passionate and headstrong approach to life.
(#4) Cancer (June 21 - July 22)

Least Compatible Signs: Aries, Libra
Opposite Sign: Capricorn
Cancers are said to be least compatible with Aries and Libra, with their opposite sign being Capricorn. A Cancer involved in a relationship with an Aries and/or Libra might find things to be a bit too unstable. Aries is fiery and forceful, and Libra often seeks variety -- and in both cases, a practical, stability-loving Cancer could become uncomfortable.
Cancer and Capricorn certainly proves a challenging relationship for both, as the Cancer is quick and open to express emotions, while the Capricorn is often stoic and has trouble expressing feelings.
(#8) Scorpio (October 23 - November 21)

Least Compatible Signs: Leo, Aquarius
Opposite Sign: Taurus
Scorpio's least compatible astrology signs are Leo and Aquarius. With Leo, a Scorpio might sense a kindred spirit - at least on the surface. Both signs are powerful, but the same great traits that make them what they are can also tear these two apart. Scorpio might also have trouble with Aquarius, as both signs are stubborn.
Taurus, the opposite sign of Scorpio, isn't always the best match: the Bulls can drive the Scorpions into a passion at first, but they'll argue later.
(#10) Capricorn (December 22 - January 19)

Least Compatible Signs: Aries, Libra
Opposite Sign: Cancer
The least compatible astrology signs for Capricorn are Aries and Libra. Here's a good way to sum things up: With Cappy, slow and steady wins the race. With Aries, it's all about impulses -- quick decisions (often without a lot of forethought) get results the fastest. Capricorn might find it tough to control Libra.
Capricorn's opposite sign is Cancer: These two are vastly different signs. Capricorn is reserved and doesn't easily express feelings; Cancer is incredibly emotional and demonstrative. Bad combo, in most cases.
(#12) Pisces (February 19 - March 20)

Least Compatible Signs: Gemini, Sagittarius
Opposite Sign: Virgo
The least compatible astrology signs for Pisces are Gemini and Sagittarius. With Gemini, the Pisces might have trouble understanding their thought processes. Pisces often rely on non-verbal cues -- Geminis are all talk, almost continually. Sagittarius' no-nonsense, gung-ho approach to tackling virtually anything in life might freak Pisces out completely.
Pisces's opposite sign is Virgo, and this match could be particularly inharmonious. Why? Put simply, Pisces is a dreamer, a person who relies a lot on gut instinct. Virgo is one of the most practical signs in the zodiac -- they are analysts who need solid facts to negotiate their life.
