I’ve always said if you wanted to kill Superman, you lock him in a dark safe deep underground for a few months without any sunlight, then open the door and shoot him in the head. Obviously that would be too easy of a death for any comic book or comic book movie, so they always have to come up with elaborate ways to fight Superman. In Batman V Superman, it sounds like Bruce has some green help in the fight.
According to Batman-News, the Bat-Armor that we saw in the SDCC teaser footage will be laced with something:
There are two Batsuits (weâ€™ve seen them both before â€” he has a traditional Batsuit, and an armored Batsuit like in â€œThe Dark Knight Returnsâ€).
The armored suit has Kryptonite all over it, and it can shoot missiles.
I wonder how the “no killing” crowd will react to Batman firing missiles…
