Rikon was formerly a Toa of Sonics, but is now a Toa of Shadow, after his light was drained by the Makuta Vyrax.
Rikon came to Metru Nui from a far-away eastern island. After arriving in Ga-Metru, he was attacked by Makuta Vyrax, and his light was drained by a Shadow Leech, turning him into a Toa of Shadow. He was then taken by Vyrax to the Makuta's hidden lair under Ga-Metru.
