Silver has germicidal effects and kills many lower organisms effectively without harm to higher animals Strengths
-SilverMan is malleable, Therefore he can bend more then a normal person can!
-It has the highest electrical and thermal conductivity of all metals. That is why we gave him red hair to present fire or extreme heat. His hair can conduct heat rather quickly and start a fire anywhere he wishes! (His hands can shoot fireballs at his opponent as well!)
-SilverMan is also very strong!
-SilverMan can also conduct electricity very well!
-SilverMan can also reflect his opponents powers back on his opponent because Silver has the highest optical reflectivity of any metal.
