You could not really say there is one important star in Orion. The constellation itself is the most prominent in the sky when it is visible, being unmistakeable and spectacular. Rigel is the brightest star, so it is important. Betelgeuse is next in terms of brightness and is a very interesting star to astronomers due to its large size and instability as a red giant. Other stars are interesting too. Then there is the Orion nebula, which is not a star, but is another major thing of interest in Orion. Orion's Belt with its three main stars is also interesting. They act as pointers to Sirius in the constellation Canis Major, the brightest star in the night sky, and to Aldebaran in the constellation Taurus. So Orion is full of interesting things, and this is why you could not say anything is most important.
