High-tech suit of armor that Krana control telepathically. Each one can tap into the krana's mask power and amplify it exponentially. Forearm design belongs to Ids5621, who used it on his self moc.
This moc is one of my favorites due to its realistic anatomy. It has ribs, obliques, and abdominals which are rarely seen in BIONICLE mocs. The secret to designing these features is to use the Technic tri-axle hub as it allows one to curve the frame.
