Generally, magnetic monopoles searches assume it has a mass. And that introduces gravity into the game. But, my question rough is:

Why should a magnetic monopole have a mass or any other gravitational/particle physics property if generally speaking they are topological in nature? Does it means magnetic monopoles also gravitate even if considered topological defects?

Related to this question: if magnetic monopoles do gravitate, what kind of "particle properties" do they have beyond mass? Helicity? Chirality? Spin?

**In summary:** why a (gauge) magnetic monopole should/could have mass and any other particle physics property like angular momentum (spin), electric charge (becoming a dyon), helicity or chirality, weak charge, color, etc? Does it extend as well to gravitational monopoles with NUT charges or similar?
