I mentioned along time ago in an admin deleted post my thought that Zaraki was so powerful because he may have been a hollow of vasto lorde strength that got purified and had his dormant power awoken a bit when he gained shinigami powers. If you look at Yachiru's shikai it even looks like a hollow split in 2. My guess is that he looks so much like Aizen did when fused with the hogyoku and became more hollow like because he has a fused shinigami/hollow power as well.
