If Toho is smart they should let WB/Legendary continue to make more films to the monsterverse, it only helps them put more money into their own pocket/Godzilla shared universe.
Can you imagine if they had two Godzilla universes going on at once, it would be both amazing and unheard of. I can't think of another where there have been two universes of the same series going on at once at the same time!
This could be the first one to do it but we won't know until after Godzilla vs Kong (2020), if it make tons of money I'm sure Toho will keep it going they would be crazy not to.
So the director for KotM actually wants Biollante and Gigan to appear in the MonsterVerse next. Awesome!
Yeah I read about that, give each of them a vs film against Godzilla and then spin the two off against each other in their own film, I've always thought Biollante should have had her own spin-off films and having one where she takes on Gigan herself would be perfect.
I can also see them doing a Biollante vs Hedorah movie as well too!
They really do need to get these two into phase 2 of the monsterverse.
