15 Potential Plot Twists That Could Ruin Upcoming Movies
7. The Joker Is Jason Todd - Suicide Squad​
The Twist: The Joker turns out to be Robin himself, Jason Todd. You see, there was an original Joker, who kidnapped Todd and tortured him until he went nuts. Batman then killed that Joker, at which point Todd then became the new Joker played by Jared Leto.
And that is why, despite Batman wantonly killing people in Batman v Superman, The Joker is still alive. He is Robin, and Bruce can't bring himself to take down his former comrade.
Why It Could Ruin The Movie: Though it's a very interesting theory and has the potential to be brilliant, it's also incredibly risky and, considering the fairly unsteady hands guiding the DC Extended Universe at the moment, hard not to be skeptical that something so complex could come across more as clumsy and confusing to general audiences. Plus, some will inevitably express disappointment at the movie's Joker not being the "real" one.
How Likely Is It?: This one could also go either way: it's not a sure thing, but the compelling evidence in its favour makes it impossible to discount. 5/10
