- “Well, that solves two problems. Now, if only we knew how to make Lex mortal again. We need his kryptonite."
"Not kryptonite—jarhanpurium. Fragments of that planet must have made it to Earth. It would be toxic to Lex; just like kryptonite is to Supergirl.” - ―M'gann M'orzz and Querl Dox, Rebirth
Jarhanpurium is a mineral from the destroyed planet Jarhanpur that affects Jarhanpurians in a manner similar to the way that kryptonite affects Kryptonians.
History[]
In 2020, Lena Luthor created synthetic Jarhanpurium with the same technology she used to make her synthetic kryptonite so her friends could use it to weaken Lex Luthor, who had not only absorbed the powers of Rama Khan, Sela, and Tezumak through an experiment but also their warned as well. A small battle between Lex and Kara's teammates broke out in the Fortress of Solitude so they could stop Lex from causing his own Crisis.
Alex Danvers successfully shot the superpowered Lex with Lena's synthetic Jarhanpurium, thus depowering him, but not before he banished Kara Danvers into the Phantom Zone The Phantom Zone projector.
