Recently I regained interest in Bionicle moc-ing as well as some other figures I grew up with when I was even younger so I decided to make a Bionicle moc with a trans-blue and lime color scheme.
Speeding under the water using their bladed tools to steer them
Standing upright
Also while building it decided the story of this character is they are a being of sentient water that one day intertwined themselves with parts of a sunken submersible robot to make a new body (the transparent parts are supposed to be suspended water and the other parts are held/moved by the water). She did this to meet the inhabitants of the surface and help those in need of rescue and/or protection.
