Starkiller's lightsabers

In 1 BBY, a clone of Galen Marek wielded two identical lightsabers on Kamino where he trained under Darth Vader. After escaping from the cloning facilities on Timira City, the clone aggresivly used these weapons to free Jedi Master Rahm Kota on Cato Neimoidia seeing the clone use the weapons to kill a ferocius Gorog beast. Onboard Alliance frigate the Salvation (Nebulon-B), the clone used his lightsabers to dispatch countless terror droids under the command of Boba Fett to rescue Captain Juno Eclipse.

On Kamino he tore through countless stormtroopers and other infantry as he intended to search for Eclipse. He eventually caught up with Eclipse, and duelled with his creator, Dark Lord of the Sith Darth Vader. After the battle which saw the Rebel Alliance win and capture Vader, it is unknown what happened to the clone and his pair of lightsabers.
