Dimensionality: 3-D | 3-D | 3-D | 3-D | 11-D | 11-D
This part is wrong, they shouldn't have 11-D dimensionality. The reasoning behind this level is this scan: https://static.wikia.nocookie.net/vsbattles/images/e/e3/PicsArt_05-03-07.13.10_%281%29_%281%29.jpg
While it does mention 11 dimensions, if you read it carefully, you'll notice it actually says they are "located between the membranes of the dimensional universes we call the 10th and 11th dimensions". This means the place is not on the 11th dimension, at best you could argue it is a 10+1-D case, but in said scenario, the +1 indicates a temporal dimension rather than a spatial one, and dimensionality is defined by the number of spatial dimensions not temporal ones. So, their dimensionality should be downgraded to reflect they aren't in the space of the 11th dimensions.
