Mr. Summers is the geology teacher at Smallville High School. He is the abusive father of Eric Summers. His treatment of his son is what caused Eric's social isolation and subsequently causing him to develop psychosis.
His son Eric, whom he verbally and physically abused, was a student in his class the day that he was stuck by lightning. He and his son were not getting along well before the accident, but after the accident, Eric was super fast and super strong and in over his head. Mr. Summers tried to take Eric to see a friend of his who worked at Metropolis University, but Eric flew into a rage. In the end, he had to take his son to an asylum.
