The issue with multiversal characters and threads is the fact that "multiversal" is itself a level with huge differences between the low end and the high end. You can go from Zen-O where there's a small, finite amount of universes with set sizes that can be destroyed, all the way to Elder Scrolls and Transformers bullshittery where there's an infinite amount of infinities stacked on top of each other while still not being enough to be considered 'megaversal'. Sure, it may sound simple: just have classifications based on the size of the multiverse! But there's also the issue that arises in that multiverses are just, well, multiple universes. When we don't have anything of the sort for any other level (we don't have multi-city level, for example). And the power needed to bust multiple universe depends entirely on the power needed to bust the universe in question, since in most cases "multiversal" is mostly a range question. Usually universes and the like are assumed to be finite...
