Zenkai is the ultimate mastery of a Final technique, like the Saigo no Getsuga Tensho. Picture it this way: if Ichigo had a Zenkai and used Saigo no Getsuga Tensho against Aizen after he fused with the Hogyoku, and Ichigo only had a Z.S.R. of 25% (see Z.S.R.), Aizen and the Hogyoku would no longer exist. That's the power behind it. Hikaru's Z.S.R. is only 16%, and he could basically create spiritual highways between the Soul Society, Hueco Mundo, and the World of the Living if he gave everything (spirit energy, life force, physical being, etc.) The event which sends Hikaru Universe hopping is created by a backlash where he countered a power of equal force, and is sent off to another universe as opposed to another world.

To start Zenkai training, N must first realize his Final Technique. then, he must go through an uninterrupted Jinzen (exact time explained in Method to Obtain). afterwards, it's 5 years of learning to maintain the power of Zenkai.

Huh? really? I didn't notice. And I'm not planning on leaving the wikia.
