Oh sorry 26, it's been a while since I've seen that episode. But we have no proof of multiple dimensions at the moment. String theory is still hypothetical and has no solid evidence, same deal with multi-dimensions.

He could just be using his powers to make his body appear that way, you know. It might be something that Bellicus and Serena agreed upon eons ago, without the need for Ben's intervention. Or it could be what the first Celestialsapien was like, and it was passed down to the whole Celestialsapien species.

That's an interesting point, but it doesn't explain how he has the ability to make his body appear that way in the first place. The reason why I thought he isn't normal matter is, in So Long and Thanks for the Smoothies, when Argit taps Alien-X you hear a hollow echo-y sound. Even if he's normal matter, it doesn't seem like he's composed of an element that most lifeforms are composed of at any rate. Perhaps something like electromatter from Futurama (which could explain why he wasn't destroyed along with the Universe), and Ben 10 has made countless Futurama references before.
