Don't turn the first sentence into a title. Titles are supposed to be a short name for the topic, not the whole idea in it.
On topic, Infinity Moment is strictly NON CANON. The IM version bosses are listed on the Infinity Moment page to have minimum amount of IM content on articles about canon content.
As for the bosses, not all of them are officially named, while some are field bosses that did not have ザ in their name as far as I remember.
