TREVCO: SUPERMAN UNIVERSITY T-SHIRT From Trevco we have the Superman University T-Shirt. This is a 100% cotton heather grey t-shirt with the Superman University logo done in black. Superman is most vulnerable to Kryptonite, mineral debris from Krypton transformed into radioactive material by the forces that destroyed the planet. Exposure to Kryptonite radiation nullifies Superman's powers and immobilizes him with pain; prolonged exposure will eventually kill him. The only mineral on Earth that can protect him from Kryptonite is lead, which blocks the radiation. Lead is also the only known substance that Superman cannot see through with his x-ray vision. Green Kryptonite is the most commonly seen form but writers introduced other forms over the years, such as red, gold, blue, white, and black, each with its own effect. Superman has also been regularly portrayed as being vulnerable to attacks of a magical or mystical nature. T-Shirt Attributes *100% Cotton *Some sizes might not currently
