What about a Taurus Slytherin? Taurus is an Earth sign which helps mellow out the Water in Slytherin. But the Taurus sign comes with its own struggles between two sides. They are warriors for the causes they believe in and are very warm and loving to those they deem worthy.
Gryffindors are the action house. Hufflepuff is the earth house, not Gryffindor. But still, Taurus seem to have far more in common with Gryffindor house members than not. Here are just a few of the major traits Taurus and Gryffindors have in common, along with a few that vary quite widely.
