Should the Monsterverse finally introduce Gigan in the Godzilla x Kong sequel?

Well there is no need for that because Gigan will appear in the new MonsterVerse anime: Monarch G-Team 

It's not an anime since it's not made in Japan lol and Monarch G-team were pointless characters. Also hire Jared Modina for the Monsterverse films please and let him do the job since his work is way better than the other artists who worked on the previous films especially for the Toho monsters lol. It's clear that he’s a fan and knows the monsters better than the directors.

anime doesn't need to be in japan, other countries might as well make their own anime!

Anime specifically refers to a style exclusively in Japan by the Japanese. It's simply called animation in the western world since they can't adopt the same style the Japanese can no matter how hard westerners try. The Last Airbender is a great example not being qualified as an anime

then what should we call it (not a cartoon)

I also think it’s a good idea to integrate it.

On the whole anime vs cartoon vs western animation front. The Japanese consider all things animation as anime that includes Bugs Bunny, Spongebob and Shrek

Last Airbender is simply an animation series not an anime. Japan does not consider those as anime. Those are simply cartoons and Shrek is an animation movie. Even if you look those up they’re categorized as either cartoon series or Animation. Anything western is not Japanese or anime.

Anime is short for animation :skull:

I honestly think that Gigan should be in Godzilla X Kong: Supernova and have a real official trademark license by Toho and have him as the real villain in the Monsterverse movie and the director, Grant Sputore and the writers, David Callaham and Michael Lloyd Green to rewrite the script, rewrite the story, and rewrite the screenplay for the movie also in addition to Gigan, they also require Mecha-King Ghidorah as the ultimate villain in Supernova and seek revenge on Godzilla and Kong and prepare for conquer the Earth in the name of alien empire and onslaught upon the enemies of Earth. Don’t get me wrong I like Spacegodzilla but I love Gigan more because he’s been around since the 1972 and 1973 movies he made successful hit. I it’s better if Legendary and Warner Bros studios would hold Spacegodzilla and have him skip from Supernova to the 3rd Godzilla movie and come back as bio-clone of both Godzilla and the other new deadly space titan that Legendary should also come up with new original idea for the space titan who will be Spacegodzilla’s birth mother. Titanus Zula’Oak or simply renamed her as Zula’Nrah, the Death-Devil Who Born from the Black Star. The name of this new space titan that I’ve thought of it, she came from my dream and I thought of new story telling and I thought of the new original character for the Monsterverse to be interested in. But I wanted to let everyone know that the new idea of the new character is not fan made, it’s the new character idea and I hope Legendary will get this comment in time and I hope they’ll understand of what I meant. And I hope there’s still time to make the decision for Gigan, Zula’Nrah, and Mecha-King Ghidorah to be official villains for Godzilla X Kong: Supernova and have Spacegodzilla skip Supernova to 3rd Godzilla sequel and name the new movie, Godzilla: The Rise of the King and have movie development in mind 2028 and release date in March, 2029. Thank you for your time and patience. Sign Chris J Velasquez. P.S and I really want to see Phosphera to have second chance to join Godzilla, Kong, Mothra, Rodan, Anguirus, and Quetzalcoatl on the Earth Team to save the Earth and humanity from extinction and destruction by the evil empire and space titans.
