Going from the trailer... It feels like a mix of G-Gundam and Build Fighters for the plot, but I'm not going to pretend that I can predict what's going to happen since it's Anno and the first FLCL writer
i imagine it's probably standalone. there aren't actually a ton of timelines where this style of colony is the main thing, and the mechanical designs look too wildly different from anything preceding
The Ad Stella timeline for G-Witch has a lot of potential in it, but they'd probably have to get permission and collab with G-Witch's writers to play around in that timeline toybox
yeah the names in 00 are especially wacky half because the mcs all use code names and half because there's a really insane naming scheme with this one other faction
And it's implied the reason why they're going full CGI with the Gundams now is because the G-Quack (calling it this because it's funnier) would be difficult to draw for animators
