Dangai Ichigo would easily beat anyone from Naruto to date and virtually anyone from Bleach.
" Dangai Ichigo meaning after his FGT training but not in Mugetsu mode? Ya he beats most everyone in the HST. Perhaps the Sage of Six Paths or full power EMS/RInnegan Madara might stalemate or beat him, but thats pure speculation. "Yeah I agree. Only the legendary figues of the HST could possibly beat Dangai Ichigo. Rikudo Sage, Possibly Maxed out Madara, Hougyoku Aizen, and probably Bankai Yamamoto. Those are about all I can think of who would stand a chance.
" @taichokage: hey i was thinking cant anyone else aside from ichigo learn the Final tech of their Zam cause whem ichigo gets his powers back the powergap betwen him and the others is going to be inmense "My thoughts exactly. Even the captains would be novice-like in comparison and only the extreme elites like Shunsui and higher could even be of any help. However I doubt it. It took most of them centuries or decades to learn their bankai whereas Ichigo learned it in 3 days. It Took Ichigo about 20x as long to learn the dangai strength and final technique so it would probably take millenia for most captains to learn it or centuries at least. I think Only Yamamoto and guys like Isshin know it. But even then, they have not shown as much base power as Ichigo so maybe they don't know it to the same extent.
