Found this guy today and decided to pick him up. I never planned on getting any of the Cyberverse warriors, but I like this guy's robot mode and I doubt we'll ever get another toy of him. Robot mode is nice and his articulation isn't horrible. Ball joints in the shoulders, hips and elbows plus hinge knees. His head is on a panel that I assumed was either part of the gimmick or done for transformation, but it doesn't appear to part of either. It seems like neck articulation could've been worked in. His biting gimmick is activated by pulling down on his left shoulder. The gimmick works well and stays locked in when not in use, unless you tug hard on the shoulder. Looks a little dumb in my opinion, but the gimmick isn't why I bought this guy. Transformation is very simple and makes a nice looking robo shark. His hands are still somewhat visible in this mode, but probably would be less so if you rotated the arm fins like you're supposed to, oops... Interestingly, the lower jaw of the biting gimmick does not form the lower jaw of the shark mode. I assumed that was why his head was on a lifting panel, so it could be folded up and then the jaw in his chest, but nope. Overall, Hammerbyte is a decent figure and I don't regret picking him up. Now if only we had a toy of Spoiler the Cthulhu Titan from his episode to go with him.
