Palamecia is the name of his kingdom. Mateus is his actual name.

His popularity in Japan also likely comes from the fact that his backstory was greatly expanded in a Japan only novelization. Also a lot of what makes other villains popular he did as well.

For example, like Kefka he poisoned an entire kingdom.

Also he not only takes over Hell, but Heaven as well at the same time.

Finally "Uboaaa!"/"Ungaahhhh!"
