There are rumors of an Evil Vagan Gundam potentially making an appearance in this story arc.
Or... it could be this.
AGE-2 Pirate Version.
(Really, Gen-3 is sounding more and more like it's out of its goddamned mind.)
That AGE-2 Pirate Gundam is the Kita Gundam and it's pilot is Asemu. As for what happened to Asemu, anyone who has read up on the manga Mobile Suit Gundam AGE: Memories of Sid or actually read it would know that Asemu's final mission before going missing was a mission to stop the space pirates Visidian and that his MIA status was a cover-up for Asemu to secretly join Visidian. So it's official: Visidian is appearing in the TV series, which also means Wivik and the G-Xiphos might appear. SUBARASHII!
