Superman is back and this time he’s fighting one of his greatest enemies. Metallo is a being that has defeated Superman many times over the years. With his kryptonite he’s Superman’s deadliest foe. One good punch and Superman could be down for the count. Of course Superman makes up for this with his kryptonite proof suit. Now he can take Metallo down once and for all. Metallo will probably be back, because he is too dangerous and powerful to be kept down. Metallo will survive. Superman wins.
