Jalkis

Jalkis was a Suroban who captured the crew of the Seamancer.

History
Jalkis helped to capture the crew of the Seamancer. Unlike the other Surobans, Jalkis tried to stop the execution of the Tenth Doctor and Martha Jones and tried to help them return to Earth. Jalkis secretly worked with the Doctor, but Kook , an angry crew member, made a bargain with King Alalal. This deal would eventually lead to the battle against Jalkis and the Surobans. Later, the Doctor persuaded the Surobans to live like Jalkis and help him recover from the attack that was made by King Alalal. (DWA: Shipwreck!)
