Recline

Spoilers Ichigo is the exception to every rule, him being abit of everything , including royalty (his father is shiba amd nobles have more spirit power) his hollow was a vasto lorde, his mother a Quincy with powerful blut veine and his father being a Captain class Shinigami. He inherited all of that , learned control during fullbring arc and finally got his true original strength during tybw. Ichigo was overpowered from the beginning but his quincy powers sealed most of his true strength away from him.(to protect him) Till he finally got his true shikai. Plus the fucker's bankia and shikia ablity although has energy based abilitys ,due to Quincy, true ablity is to break fate....... What makes Ichigo great tho is that he isn't god from the get go and attaining bankia nearly killed him(he was injured before his fight against Kuchiki, bandages and stuff) ... Sure his original true strength is dam lot but it is the equivalent of giving a shotgun to a 3 year old . Without understanding and trials and training he would not be able to use his full strength and even then his power is still growing during tybw.
