Emperor Joker's physical manifestation

So at first, I believed Emperor Joker to be a 5-D being. So I asked Ant to categorize him as a higher-dimensional being. But after searching around, I found Zach's comment on a thread. He said:

"To be fair, Joker isn't a 5-D being, he just temporarily gained 5-D magic"

If what Zach said is true then Joker should be removed from that category. If not then Joker should have Higher-Dimensional Existence on his page.

Here's the thread with his comment: https://vsbattles.com/vsbattles/2402761

I removed the category from his page. It is probably better to do so if it is uncertain whether or not he qualifies.
