Batman: Arkham Knight - 10 Perfect Ways To Kill Batman

7. Scarecrow's Bomb

With Arkham Asylum it was the Titan formula, with Arkham City it was Protocol 10, and with Knight it's Scarecrow's chemical bomb. Indeed, it wouldn't truly be an Arkham game without some big, ever looming threat hanging over the player's head for the story's duration. Biological weaponry is enough to send anyone into a frenzy just by being uttered, so the prospect of Scarecrow actually using the bomb is a pretty frightening one (even if he's evacuated the city for some strange reason). The bomb's qualities aren't really known, but as with any chemical or biological device, the potential for fallout and further contamination across a large area is high. If Scarecrow actually detonated the bomb in Gotham, there's a huge chance it may become uninhabitable - lest its residents feel okay with reliving their worst nightmares on a recurring basis. The chances of Batman meeting his end this way are much lower than that of the other choices on this list, namely because it was already done in Nolan's third Batman film. Still, it would be interesting to see Batman have to deal with the effects of Scarecrow's toxin again - especially if he was able to overpower it much in the same way he did when the two crossed paths in Arkham Asylum.
