Dax-Ur owned a shield in the shape of a Kryptonian pentagon.
Powers and Abilities[]
When the shield was held in Clark Kent's hand and Dax-Ur's name was spoken, Dax-Ur's shield emitted the high pitched sound of a Kryptonian beacon and teleported him to Dax-Ur's location.
Brainiac was able to hear the sound from Suicide Slums, signifying that the beacon sound has considerable range.
Early History[]
The shield was brought to Earth by Dax-Ur, one of Krypton's greatest scientists. He lost it a century ago, and it somehow ended up in a time capsule buried in Smallville.
Season Seven[]
The Weather Girls came to Smallville, looking for a treasure map to a hidden time capsule. It supposedly led to millions of dollars of gold bars. They entered the "Miss Sweet Corn" beauty pageant as a distraction.
Clark and Kara recovered the shield from the time capsule. Clark learned how to use the shield from Brainiac, who was posing as Lionel Luthor, Jor-El's emissary.
Clark then used the shield; it emitted a beacon while it teleported him to Dax-Ur's location.
