And I seriously doubt Alexander being summonable... even more so this update and that being the summoning model.
Meh... people said the same exact thing about Diabolos...everyone and their mother kept telling everyone it will never happen, they wont add new summons, same elements, blah blah blah. So its silly to think that a known avatar from ff past, in model form,
that is about the same size as other avatars in the game, not be summonable at some point..
SE
said there
will be new avatars, which ones, they said they were looking into it. I think this is the first indication of the possible next avatar. And just because he is hinted at being related to automatons doesnt eman he couldnt be an avatar. I dont remember the directly calling alexander a automaton anyway. But even if he was, if an avatar can put her power into a sword, im sure they can do it with a robot.
