BIONICLE's had some pretty neat concept since its inception back in 1999 as "Bone Heads on Voodoo Island" to 2015 and 2016 where there was some really stellar concept art, if you would even want to call it that.
Which year's concept art did you really enjoy? Do you like concept art? Is there any concept art that tickles your nostalgia?
I know I enjoyed Gen 2's concept art, as it is really art. But there are some that just get me right in the feels.
