Sy-O

Sy-O was an exogorth that lived a solitary life in the "Big One" asteroid within the Hoth asteroid belt. Sy-O was over one billion years old by 3 ABY, which was young for an exogorth. Sy-O attempted to capture the Millennium Falcon and its crew in order to make them a part of their internal ecosystem and meet the social standards of its kind by having a more diverse ecosystem.
