Vohon was a Ta-Matoran.
Vohon continued to be a Trader; he sold and bought some items from Hahli while she was visiting Ta-Koro. After the Kolhii Championship, Vohon was evacuated from Ta-Koro along with the other Ta-Matoran when it sank into the Lake of Lava.
Return to Metru Nui
He later returned to Metru Nui and helped to rebuild it until the Staff of Artakha did the rest. He was also present during the ceremony to honor Matoro's sacrifice.
After the Battle of Bara Magna and the death of Makuta Teridax at the hands of Mata Nui, Vohon evacuated the heavily damaged Great Spirit Robot along with the other Matoran and migrated to the newly-reformed planet of Spherus Magna.
Powers and Tools
As with all Ta-Matoran, Vohon possessed inaccessible Elemental Fire powers; this manifested in the form of a natural resistance to heat and fire.
