Szayel Aporro Grantz

The Octavo Espada, I never thought I’d see a mad scientist character that would creep me out more than Mayuri Kurotsuchi. There are just so many examples. But I’d say Szayel Aporro eating his own Fracción to heal himself pretty much outdoes Anything Mayuri has done so far (yet I do expect Mayuri will pull something even creepier before the series is over). Mayuri is the better mad scientist, but Szayel Aporro is still pretty darned good at giving someone the heebie-jeebies.
