Vorahk is an antagonist who appeared in the Bionicle series, acting as one of the main antagonists in the 2003 storyline. He was one of the three Rahkshi created by Makuta Teridax to stop the rise of the seventh Toa.
Vorahk, Turahk, and Kurahk tracked Takua to Onu-Koro, where they fought both Onua and Pohatu. Vorahk succeeded in draining Onua's Toa power, but due to Pohatu's intervention, Onua was able to regain it. Onua put and end to the fight by bringing down the ceiling of the Onu-Koro caves, seemingly killing the Rahkshi.
However, Vorahk, Turahk, and Kurahk all survived and rejoined Lerahk, Panrahk, and Guurahk. They followed Takua and Jaller to the temple of Kini-Nui, where they attempted to corner and kill Takua. The Matoran were saved when the Toa Nuva arrived and defeated the Rahkshi one by one.
Vorahk's body was later used to build the Ussanui.
