Bionicle MOC: Ryakk 4

Ryakk-dark hunter and all around badass. He is 2nd in command in an elite squad of Dark hunters that are the brother hood of makuta's Go to guys. They answer only to Teridax, and they barely do that. Ryakk has a nice arsenal of weapons. He has his spinning power axe, a smaller secondary axe on his back, he also claimed the spear of fusion from vezon. When a Massive dark hunter that's four times your size wants something of yours you give it to him. In the process of taking the spear of fusion which he uses as a dagger he also killed the kardas dragon and made its head into shoulder armor. Ryakk also has some elemental energy grenades. Another noteworthy artifact ryakk has obtained is a crystallized Kanohi Avohkii. If this crystal mask has any power's he's yet to figure out what they are. Simply liking the artifact he wears it as a necklace ornament. He may be very big, but he is by no means slow. He's agile and can be aggressive, but is also not a brute. If he can't get the job done with strength alone he'll surely get it done with intelligence and cunning.

Ryakk is the first Colossus I built and stands about 2' even(give or take a little) He originally started out as a modified Kikinalo that I just kept working on. I've been working on Ryakk now for about 6 years. He really took his more current form in 06 as seen here [link] When updating him I make sure to keep just 06 and previous parts on him.

Edit
Here we have ryakk with the spear of destiny that he modified into a dagger for himself, and his smaller secondary axe. Ryakk either uses these in combination or one at a time. The dagger is best for quick maneuvering and instant kills. The axe can be thrown and is a little heavier, but still very fast to use. A couple of jabs to the chest with either weapon will ruin someone's day.
