The Green Kryptonite Palak or Green Kryptonite Starblade was going to be a weapon made out of Refined Green kryptonite that was a theory Lionel Luthor came up with to make a duplicate of the original Palak, also known as the Star blade.
Season Three[]
Lionel told Clark he wanted to make a duplicate version of Palak, just like he made a duplicate version of the ship's Key by making the Kryptonite Key. His scientists never ended up creating the duplicate, because the original was destroyed before they had a chance to analyze it.
