Previous Post ANY ever listed as such in the DCU?

There was a Kryptonian Sect in Pre-Crisis continuity called the Wizards of Juru. They operated in secret and were in hiding from the rest of the 'technological' society of Krypton which shunned magic. The only survivor of it was named Thul-Kar, who managed to transport himself into the Phantom Zone before Krypton's destruction in order for the society to survive.

But he was trapped and essentially become a servant to the consciousness of the Phantom Zone called Aethyr (in fact, when he tried to defy him, his face became disfigured).

As far as I know, his first appearance was in the Phantom Zone mini-series and his second (and only other appearance) was DC Presents#97.

But yes, there were Kryptonian Sorcerors
