Essentially he is the same as Great Thing, except that he now has a slow circular path he moves about in. This means that you don't always face his full wrath, which is somewhat of a good thing. But don't relax...his attacks are as relentless as Great Thing as well. And, as in Super Darius, since the screen is smaller (and this is unique to HGT) he moves all over it, you have less elbow room and can get crushed by him. But don't be discouraged too much.
