Ok. Bear with me I am a newbie, and I don't know if someone has already asked this question.
When a heart is taken from someone, a Heartless and a Nobody is produced, but If the heart of an individual is strong, a strong Heartless will be produced. My question is, since the Organization is composed of powerful Nobodies, would that also mean that somewhere along the line there are 12 *excluding Sora's* powerful Heartless of the remaining 12 members? I ask this because Xehanorts Nobody is Xemnas, and his Heartless is the Ansem fought in KH1. Which makes me believe there could also be an Axel Heartless for example. Is this a legitimate theory or is it just me rambling due to confusion
