I don't know who the Giant was in the armor, but I'm pretty sure he was some sort of "Frankenstein" that one guy was working on in his lab. We only get a glimpse of somebody that's covered up with a cloth on a table, suddenly kicking and making a commotion. So, I'm guessing they are one and the same. So now they have the ability to bring back the dead. Who else will they suddenly bring back? Hmmmmm........ FYI, I want to see more of Wun Wun!! That character looks f*cking awesome!!
