The Toa HQ, or Toa HQ 4, was the second-largest HQ in the Old BIONICLE Roleplay Subforum. The Makuta HQ 3 was its main enemy. It was allied with the Order of Mata Nui HQ 3 and had over 400 pages. The Makuta once occupied it and turned it into a fortress, though due to the island's near destruction in a storyline, the HQ was abandoned. The HQ has since been deleted.
