Frequently asked questions
- What are Fikou in Bionicle?
- Fikou were spider Rahi created by the Makuta. On Metru Nui they lived among the cables of Le-Metru and Onu-Metru, lurking in high branches and tangled cables and waiting for their very strong webs to catch prey.
- Why are the Maintenance Tunnels called the Fikou Web?
- A section of the maintenance tunnels below the Onu-Metru Archives is called the Fikou Web, both for the webs the spiders left in the passages and because the tunnels themselves are laid out like a web.
- How dangerous were Fikou?
- Dangerous enough. They could jump out to catch passing prey, and on the island of Mata Nui some were controlled by Teridax through infected masks and attacked Matoran.
- Where else did Fikou live?
- Many Metru Nui Fikou moved to the jungles of Le-Wahi on the island of Mata Nui, and a sub-species with pincers and a stinger lived on Voya Nui.
- Were Fikou ever made as a set?
- Yes. A black Fikou could be built by combining the 2001 Toa Mata sets Pohatu and Onua, and an orange one came in a 2002 Master Builder set.
