All Ultramen vs DaiKaiju

Heisei Ultras UNITE! Now I really gotta get those Ultra-Acts of Zero, Ginga and Victory

Oh, cool to see Nexus here... Is this his first appearance since his own series??

This looks awesome.. and also reminds me that I still need Nexus.. Gaia.. Max.. etc. lol.

Hey, it's Yoko/Yellow Buster!

Ginga S is a pretty cool show so hopefully this is a pretty cool movie.

Nexus is reason enough to watch it. :lol
But that does look like a sweet team-up.

Not entirely. There was Noa's appearance in Revenge of Belial, several episodes of Retsuden, and a bit in the music video compilation of opening songs, Ultraman Hit Song History. I believe Nexus is also part of the flashback giant monster fight in Ultraman Ginga, with no explanation how he showed up in that universe, but I'm not 100% sure.

This would be the first major Nexus appearance post-show, however.
