The semi-universal symbol for therianthropes. Looks like a delta weaving in and out of a theta. Some therians customize it by putting their spirit animal on the inside.

A male who is a mystic and an ascetic; a male who is dedicated to fully embodying a disciplined and purifying spiritual lifestyle. Embodies only the deepest modes of mystique evidenced in the multi-dimensional Zeta male, but without the Zeta's ability to shift modes such as rebellion mode due to permanently dedicated to the status of being a monk. Also does not feel the emotions of any of the other categories of male.
They made fun of his act but like a true Theta male, there was zero trace of any discouragement or anything reactive at all to be found in his demeanor as he withdrew from the scene.
