Superman Batman Movie: 10 Reasons Batman Would Definitely Beat Superman

3. Kryptonite Ahhh Kryptonite, one of the most stupid plot devices ever made. Oh yeah, let's make our Superhero completely invincible. Super-Strength, indestructibility, flight, speed, yeah all that stuff. Hey, isn't our guy a bit too strong? Oh yeah, he needs a weakness! How about this green stuff, that makes him useless when he's near it. Yeah sure. Maybe that's a bit harsh though, Kryptonite did serve a purpose on Krypton, it weakened the race's natural powers so they couldn't be used for evil, and society was in balance. There's no real way to ignore Kryptonite on this list. The substance causes Superman to temporarily lose his strength, and have that of an average human. In that case, Batman would just cleanly beat him in his weakened state using his martial arts and combat skills. Not to mention Batman has a stockpile of the stuff, just in case Superman becomes the world's greatest menace. It's not exactly exciting, and is the basis for at least of 50 percent of Superman's storylines just to actually present some real danger, to the otherwise immortal hero. Not much more to it than that, really.
