Also used in conjunction with other words, meta+word (or word+meta), meaning exactly metaverse+word, e.g.
Metaverse Navigator (イセカイナビ, Isekainabi)?, Meta-Nav for short,
Meta Zone (Metaverse Zone, or even just “Metas” as the shortened form of Metaverse Zones)
etc.

The metaverse has infinite potential. AI will even help to design wonderful 3D immersive spaces within the meta.
