It's been a while since its tv run or my last viewing of the BD's (which I've actually been meaning to re-watch) so I honestly can't recall if there's a difference between the two. I don't THINK there's any foul language that needed to be bleeped out but I could be wrong. If it was edited and re-rated for its broadcast run maybe it was to remove some or parts of some graphic scenes? It's hard to know at this point. Maybe this could be a question for a future Toonami Q&A.
