Batman V Superman: 15 Theories That Were Utter Bull
4. Batman Has A Kryptonite-Laced Suit
The Rumour: As soon as the movie was announced, fans casual and hardcore alike wondered, how exactly is Batman going to even the odds when he's going up against a God? The most prevalent rumour suggested that Batman's armoured suit in fact housed Kryptonite that would allow him to bring Supes down to the level of a mere mortal.
How Much We Believed It: It sounded super-plausible from the get-go. What's not to like? 9/10
The Truth: Batman instead uses Kryptonite gas to weaken Superman for the fight, as well as the Kryptonite spear to very nearly finish the job. It's functional, but not nearly as efficient as just having a suit that levels the playing field immediately. We prefer the suit idea.
