I went with the dimensional shift because I imagined he was in the middle of changing locations when the Super Paper Mario multiverse got attacked.  I can change it.

As for the "seen from the front" due to him being a 3D being rather than 2D sprite in a 3D map I was picturing his dimensional shift making him look like a line at all angles like when you look at a billboarded sprite and see the same exact flat image at every rotation.
One of the giveaways I was thinking of was that his shadow would still look normal in spite of him having a less visible form.  Another was that seeing him from [i]above or below[/i] gives him away.

Good to hear that the sheet's almost ready to go!

I think I've gotten the picture, although it's still a little confusing. I do think that simply being able to make himself two-dimensional would be a very useful Power in and of itself, without any extra confusion. Is able to become just a line in his game?
