Minor lieutenant in the Lucian Alliance. His direct superior is Netan. Worrel was responsible for the crop of kassa on P6G-452. When he was approached by Colonel Cameron Mitchell he grew suspicious that a buyer with his requirements would approach the Alliance on such a low echelon, and captured SG-1 when he believed they were responsible for hijacking 452's Stargate.
For almost two days Worrel held them hostage but was unable to gather any information. When they were transported away by the U.S.S. Odyssey he met with Netan, who ordered him to find the real Stargate thief or to not bother returning.
This was enough of an incentive to Worrel, who eventually discovered the Goa'uld Baal's location. Netan, with Worrel at his side, destroyed Baal's mothership, destroying any hope of regaining their Stargate via their actions (though SG-1, who had rescued all but one, may have returned a gate to 452).
Off the Grid - Worrel very nearly loses his livelihood in the Alliance to SG-1 after he believes they are responsible for the loss of his planet's Stargate.
