I think DarkTyranomon X takes over it. Pity BlackGreymon X will never happen. But your comment made me think hard.
BlackAgumon X's stripes. If he got BlackGreymon's stripes but reversed (Darker blue), he'd look good but less aggressive compared to red stripes which made him looked even more cooler and very aggressive. Yellow stripes? I feel nothing from that yellow color for "savage" or aggressive vibes... On BlackAgumon X.
But I'm pleased Tyranomon families (MasterTyranomon didn't get that love....) are still get strong love. I have good feeling about BlackGreymon X. In the future, he probably will get savage design with less recolored for sure.
I'm really into MetalGreymon X Virus, but i'm a little more intrigued by the survive screenshots. That mansion battlefield is really interesting, I wonder if it's going to be a full on devimon style thing? It's also nice to have daitrymon confirmed as an evolution for falcomon, and a version of the "main" image with the rest of the main cast on it
