BBC 65 - FOR THE BIRDS Kahu - Great Winged Rahi [Link to the gallery] So for those of you who are newer to the Bionicle scheme of things, Kahu was originally a species of bird Rahi which were the heavy-hitters of Le-Koro's air force. It was a combiner model for the Nui Jaga sets. Way way back in the day, I built a Kahu (named incorrectly) for a previous BBC contest, but was overall unsatisfied with the overall feel of my creation. It was too docile. Almost pigeonlike. For this contest, I tried entirely from scratch to build something more predatorial while still keeping the feel of the old set and my creation intact.
