Aris Boch

Aris Boch was an alien bounty hunter whose native species had a biological resistance to Goa'uld blending and, thus, could not be taken as hosts. The Goa'uld empire enslaved the race and addicted them to a drug known as Roshna which kept them subjugated.

Aris Boch worked for Sokar and his payment would be a supply of roshna which he would recieve upon the successful capture of his bounty. Though he does this, he does demonstrate a hatred for the Goa'uld but saw no means of fighting them and thus resigned in his fate as their servant.

After encountering SG-1, Boch decided to let his bounty and them escape even though this made him an enemy of Sokar.

Note
His species has been identified as the Illempri.
