Personally what I wonder is what are those three blue spikes on the top of the Dark Wunder, it's where the AAA Wunder has its three dishes (btw do we know what are the Wunder's dishes, aside letting Asuka and Mari practice their roller skills?), as well as what kind of weapon the Dark Wunder's' four spheres are. (since it's where the AAA Wunder has its four cannons, I guess that those are weapons)
Mark.06 was found crashed on the Moon by SEELE, which implies that it's one of the four ADAMs that somehow was ejected to space during Second Impact. Also since there are five "gods" (Lilith and the four Adams) in the Rebuild universe, it's possible that there are actually five spears instead of just two.
Honestly, before being sure at 100% about the identity of the Mark 06 we would wait for the last movie ... Anyway I hope that its presence in the dogma terminal will give an adequate explanation in 3.0+1.0...Of one thing instead I'm sure that Cassius' spear held by Mark 06 probably served not only to stop the Near Thrid Impact but was also necessary for Lilith's resurrection ...
