The lion tattoo has always been a symbol of power. Yes, there are many people who see the lion tattoo and immediately connect it to the astrological Leo sign, but there are plenty of people who see the lion as something completely different.
For one, the lion tattoo has become a very alluring image that one could almost call sexy for lack of a better word.
The forearm is usually where the lion is placed. It is usually on the dominating side of the body, which is a way of matching the lion with your strength. There are some people who see the lion as a symbol of royalty. It is a symbol of royalty because you are the king of your own destiny and the king of your own decisions. Those who see the lion as a symbol of royalty usually think that fate does not rule their lives. This makes the forearm lion tattoo a very liberating tattoo.
There are others who see the lion as a religious symbol. This stems from the times that a lion was mentioned in religious texts or in literature that used the lion to represent a higher power. The lion here is still a king; however, it does not mean that the wearer is the king but rather that there is a king, and this being must be respected as such.
