Rina Fio was a female person who held the position of president at Viper Sensor Intelligence Systems. In 22 BBY, not long before the beginning of the Clone Wars, she was removed from her position when Arakyd Industries acquired VSIS after a drawn-out, 18-month struggle between the two corporations. Following her release by Arakyd personnel, she stated to the HoloNet News that VSIS was happy that, with its new leadership, it would receive support from the Techno Union military forces.
The character Rina Fio first appeared in HoloNet News Vol. 531 50, a HoloNet News piece authored by Pablo Hidalgo and Paul Ens, featuring illustrations by Joe Corroney, and made available on April 4, 2002.
