It wasn't formed as such. Orion, like all constellations, is a group of individual stars that have no relation to each other, but from our perspective they appear to make a noticeable pattern in the sky. They are different sizes, different distances away and so on, but just happen to seem to form a particular pattern. So constellations are in effect formed through the imagination of people. We look up at all the stars in the sky and through our own imagination they look like things, so we name that group as a constellation. Orion and the other constellations were created in that way. In reality, every star in Orion was individually formed. They were not formed together as a unit at the same time. If you were in a completely different part of the galaxy, the stars of Orion would look completely different in terms of a pattern, and some may not look connected in any way. So were you halfway between two of the stars of Orion, they would be on completely opposite sides of the sky to you, so would not be part of the same patterns that you would see.
One.Orion doesn't "have constellations". Orion is a constellation.

Star formation was a one-time event. Star decay and death still occur, but stars can only be newly observed, not newly formed.
