Probably my personal favourite creation is Arachna, a Bionicle spider capable of taking on a humanoid form. "She's" Been in my collection for some years now, actually, but after some recent improvements I did I finally decided it was about time for some limelight.
About this creation
A large and slightly skeletal looking arachnid, Arachna is fierce and isn't afraid to approach prey head on using brute tactics. Her large, hooked, metallic fangs and sharp, almost sword like appendages allow her to tear through most victims with ease.
When necessary, or in times of delegation, Arachna can morph into a humanoid form more resembling the rest of the Bionicle's chosen. Such a process is simple and effortless.
Now in a humanoid state, Arachna is capable of doing as she sees fit. Don't let the appearances deceive, Arachna is still a deadly fighter. Her humanoid form allows her to utilize more flowing martial-art like moves while still being able to deploy her sword like limbs to inflict serious harm.
I'm hoping to expand on this later, with more morphing Bionicle. There's a lot of possibilities, and the outcomes can be very cool. I had a raptor-like morphing Bionicle I made a long time ago that should probably be rebuilt and improved.
Hope you enjoy the build!
