Let's get this out of the way: mass is not a dimensional unit.

What that means is that your mass is not dependent on your dimensions. You could bring up density, but that just further demonstrates the point. Density is mass per volume. The mass itself is independent of the object's volume unless you force it to keep a constant density.

You can compress the object and decrease the volume while the mass stays the same. Or you can stretch it out and increase the volume while the mass stays the same. Point being, the mass of that object is not dependent on how big the object is. A singularity is the ultimate example of this, having solar masses compacted into an infinitely small space.

The core tenant of dimensional tiering is wrong. Just because someone is 4D does not make them "infinitely bigger" than a 3D person. It's fully possible for a 3D person to have more mass and strength than a 4D one does. In fact, since the force of the 3D person's hits would transfer through the 4D body, a 3D person could literally one punch someone of a higher dimension.

Even string theory, which VSBWiki uses for their multiversal tiering, outright states that higher dimensions are actually smaller than our own. Their logic doesn't even hold up to itself.

And then we get into temporal dimensions, which they have a horrible grasp of.

Time is not the "fourth dimension". It is a dimension that is separate from our spatial ones. A more accurate description would be that time is the third plus one dimension. However, VSBWiki doesn't seem to grasp this. Going by them, any character who is "4D" or higher qualifies for any slew of time related abilities, up to and including infinite speed.

The problem with this, as said, is that "4D" does not automatically mean "literally apart of time itself". Unless the fiction shows this to be the case, there's no reason to assume any 4, 5, 6, or 20D character is anything more than "20+1D" and moves through time exactly as we do.
