Orion

• The sun of Neptune with an amazon huntress as a mother. He became the world’s greatest hunter, became overly confident, and came to a tragic end when an itty-bitty scorpion stung him.

• Another version, he got a little too close with Diana, and Apollo in anger bet his sister that she couldn’t hit a distant target. She did and it turns out the target was Orion.

• He is in the sky as a hunter attacking a bull and can be identified by his belt of three large stars.
