10 Most Underrated Superman Villains

We all know Superman is vulnerable to kryptonite. But he has another weakness that is often overlooked - noise. Because his hearing is strong enough to hear someone's heartbeat on the other side of the planet, one can only imagine how loud it must be upon hearing gunfire or an explosion.

Because of this vulnerability, one of Superman's most dangerous enemies is Siobhan McDougal. Due to a family curse, McDougal was turned into a demonic spirit called the Silver Banshee. Endowed with a Death Cry, Banshee can perform a scream that can place its listeners into a coma, drive them insane, or shatter their bones.

For all of Superman's strength, even he struggles to face this Irish supervillain. Although SB is known for her deafening scream, she has other abilities. She can teleport, fly, and is strong enough to hold her own against Superman. She is also immune to all sound attacks so Superman or Black Canary's sonic attacks can't harm her.

However, her deadliest ability is her Death Stare. If she knows a person's birth name, she can kill them simply by making eye contact with them. Essentially, if she knows Superman's name is Kal-El, he's done for.
