Since everyone missed/ignored/spoiled privious thread about Kenpachi still not fighting on his best after defeating two or 3
Lets make it clear they we're not week, they we're unlucky.
When Kanpachi fought Nnoitra ''Espada 5''
They Introduced us to what kenpachis eye patch really is
Kenpachi is the only captain of the Gotei 13 who doesn't know the name of his sword, and therefore he is unable to use his bankai. In addition, he never uses kidō and rarely uses flash steps. The Bleach Official Bootleg databook ranks his talent in the former as zero. However, he more than makes up for his faults in sheer power. His spiritual pressure is such that, even when wearing the energy-sealing eyepatch, Kenpachi can fight on-par with and defeat other captain-level opponents
Eyepatch Power Seal: Kenpachi wears an eyepatch created by the Shinigami Research and Development Institute just for him that can seal the bulk of his reiatsu, but since he has so much of it, it does not noticeably hinder him in battle; in fact, it makes him just ahead of most other captains and Espada. The reason for wearing it is that since Kenpachi loves fighting so much, he cannot fight most opponents at full strength without defeating them quickly
. Seventeen months after Aizen's defeat, Kenpachi wears a new eyepatch. Reiatsu Bells: In order to further give the enemy an advantage
, Zaraki wears bells on each spike of his hair. These bells can only be heard by enemies whose reiatsu is concentrated to the point where it can actually defeat Zaraki. Seventeen months after Aizen's defeat, Kenpachi reveals he doesn't wear the bells anymore.
Image in his new eye patch.. no indea what it actualy does, I can only guess that it can seal more or release it all at will maybe :shrug:
This last fight will be dream come true to Kenny, all he ever wanted is to fight on his max and even if he dies he probably will die happy
