Antroz is a villain from the BIONICLE series. He also serves as the secondary antagonist in 2008 storyline, with Icarax as the primary antagonist and Gorast as the tertiary antagonist. Antroz was also a member of the Brotherhood of Makuta and the Makuta of Xia.
Approximately 100,000 years ago, Antroz and the other Makuta were created by the Great Beings, using the substance known as the Antidermis. When the Brotherhood of Makuta came into being, he eventually became a member of the organization as the high-ranking commander of the army.
A few years later; when the League of the Six Kingdoms led by Pridak attempt to overthrow the Great Spirit, Antroz was assigned by Makuta Miserix to assist Teridax and their army to stop the rebellion. While Teridax and the others went to Metru Nui to attack Pridak and his allies, Antroz, Gorast, Vamprah and Bitil went to Po-Metru to launch an ambush on the army of both Kalmah and Ehlek. During the ambush, Antroz and Gorast successfully overpowered Kalmah while Vamprah and Bitil defeated Ehlek with ease.
Later after quite sometimes, Miserix assigned Antroz to supervise the island of Xia, which he later supervised its population and their activities.
When Teridax eventually succumbed to the dark side and immediately demanded a Convocation to reveal his plan and claim leadership, Antroz was the third one to side with him after Gorast was the first one to side with him.
- "Stay here and die if you like, Gorast...but i won't!"
- "Farewell, fools! I will gladly witness your deaths, but from the greater distance!"
- "No! This can't be!"
- "Even without Jetrax, i am still the most high-ranking Makuta and once the Plan is done, Teridax will rewarded me with a higher prize!"
