No Sun sign (otherwise known as a star sign) can be considered to show loyalty or who will be the most loyal according to their Sun sign. The whole birth chart of an individual has to be considered to decide on what level of loyalty you can expect from a person. However, the zodiac signs Leo and Scorpio have a strong association with loyalty.
It's hard to say, since ALL birth signs are capable of cheating.
If you'd ask me, I consider Taurus to be the most powerful sign because as a chinese zodiac animal, it has the Dragon which is the most powerful animal in the Chinese zodiac animal.
