Are we going to see some remodeled Destiny Gundam now? Maybe Sei would name it Build Destiny Gundam... hmm, maybe? no...that should be the Build Strike Cosmos.
***Basing on its back skirt, the pointy features of it looks something like Destiny Gundam's.
The one on the right looks like a modified Xi Gundam, basing on its shoulder armor, but I see a Bawoo on that model too, maybe a mix of both?
The SD GunPla has some Z Gundam like shoulders and v-fins, back pack looks like ZZ's
