I just figured something out that will blow you away. The true forms of Bionicle characters! If you know, toa Nikila was a contest winner and is canon, just like all other contest winners. She was never built as a Moc, but rather artwork. If she is canon, than that must mean that she is a good design for how bionicle characters would look in Greg's eyes. Here she is:
She looks similar to the MoL designs but you can still see elements of a real set in here, unlike MoL. Feel free to discuss what you think or if you have any ideas. Also, Voriki was going to be a male... What?
