Beel is certainly one of the toughest babies I’ve ever seen. He has lightning abilities and has only just begun to tap into his true power. That being said, with no sequel series at the ready just yet, Beel may already be at his peak. Oga just needs a single good punch to take him down for the count. By the end of the series, Oga was virtually unbeatable and his physical abilities are simply on a different level. Oga Tatsumi wins.
