The final war potential?
Yhwach, the emperor of the Vandereich, stated that there was 5 special war potentials against the Vandereich. What we know so far:
1. Ichigo Kurosaki
2. Zaraki Kenpachi
Considering Yhwach visited him while invading Soul Society, we can assume he's on the list.
Also, It seems these "war potentials" are seen as possible future allies. This means we can assume Uryuu Ishida was one of them too.
Which brings me to my question, who's the last war potential? It wasn't Captain-Comander Yamamoto so it's most likely not any of the Captains. Could it be Urahara? Leave you're comments below regarding you're thoughts on that 5th war potential or if you think Uryuu and Aizen aren't among them state your reason. I look forward to hearing from you all
Edit: Soul king? ;P
