Top Deadliest And Most Intimidating DC Villains of All Time

 Metallo

Metallo is like the opposite of Superman in terms of weaknesses. He is a radioactive cyborg intelligence who depends on Green Kryptonite as his energy source, making him a deadly enemy of Superman. This radiation is a major advantage for Metallo, but can kill the man of steel through exposure alone. Metallo’s cybernetic enhancements make him very physically powerful. He is a former soldier who was used in experimentation by the United States Army.
