I was going to post Giga as my first MOC to show off here, but I decided to opt for my Self MOC instead.
Originally created as a side character, the original design of him grew on me and eventually caused him to become a much larger and more complex version of himself, spanning over 7 versions of himself with one key look held throughout.
His build is what I would call "intermediate", where he has some simple uses for parts, but posesses a few parts that aren't so easy to assemble by just looking at him. He measures in at about 12 inches, making him about as tall as 2008's Takanuva. Despite his size, he is very poseable and is able to pull off positions most titans his size couldn't accomplish without having pistons to hold him up. He can hold himself in fighting stances , both with and without his swords... but it's a bit easier to pull off poses with them off. Much of the parts on him are built to adjust and shift (such as the shoulder armor and the numerous joints on his upper torso), giving him as much poseability while maintaining the strength to hold out his swords at full length.
Bio: Toa Kyrak has lived many lives, through many continuities: some last for centuries while some come to a spiraling collapse... but more often than not his adventures begin as a matoran, taken from a life of peace and held prisoner. The pain endured there and a transformation by a corrupted Toa Stone resulted in the deaths of his captors and his escapeto an aboandoned island. In isolation he came to control the monster he had become, and was found and befriended by Toa Icardee. On that day, he swore to do make up for his wrongdoings, claiming the name of Toa Kyrak.
Just as an added note, posing him on only one foot isn't an easy task. He is better suited to have one foot planted on the ground and one foot leaning on the toes or heel.
This was an afterthought on Kyrak, mainly added to fill up a gap that was left in his chest cavity. This "Crystal Heart" and it's accopanying Technic arm above it act as a way of making Kyrak feel more complete while not being easily noticed in most angles.
Oh, and in case you're wondering what those pegs in the center of his back are for, that is an adapter for jetpacks and other objects Kyrak could carry on his back.
(I hope I did well with this post. I'm still farily new to forum posting.)
