Tobduk

Tobduk was a 10 feet tall member from the Order of Mata Nui who helped, with his memories, create the book BIONICLE World. He was extremely strong, and could feed on rage to increase his strength. Tobduk was the mastermind behind the murder of Kojol and everybody else who knew the location of Artakha. He was in a perpetual rage and was a talented fighter.

Mazeka fought with Tobduk, and lost, on several occasions as part of his training.

When Mazeka snuck into the fortress on Daxia in order to question Toa Helryx about the whereabouts of Karda Nui, he discovered that the Toa had left, leaving Tobduk in her place. When Mazeka attempted to find out, Tobduk stated that he would only give the Ko-Matoran his answer if he aided Tobduk in a hunt.
