This is one of my biggest MOCs, that I built. It presents W'raik mutated by unique Black Brain parasite (that took the green colour after mutation) - Vreznerax.
About this creation
Vreznerax has got about 336 parts and he was built for I read EHF MOC Contest II . He contains a lot of parts from Hero Factory and some parts from BIONICLE.
Vreznerax was normal W'raik. He lived quietly and he practically didn't stand out among the other members of his class of robots. But one day his life changed dramatically. On his planet came disgusting creatures - Brains. These attacked the Vreznerax's herd and transformed all of its members in Vrazner. He saw his friends changing in the beasts and escaped, but soon and for him the time came - during his escape Black Brain pounced on him. W'raik tried to rip it out of his head, but it was too late. Control over his body took parasite, and Vreznerax transformed into a giant monster, who looks like mutated bat. Vreznerax attacked Makuhero City from the air, causing untold damage.
