Martha Kent and her husband Johnathan were Kansas farmers. They discovered an alien space ship that had crashed off the side of the road. They found inside a young boy. The boy was Kal-El, the last son of Krypton. They took the boy in and gave him the name Clark Kent.
When Clark started to develop his super hearing and X-Ray vision, she was called into the school and sat outside the closet where the young Kryptonian was hiding. She helped him take control of his powers and calmed him down. Jonathan and Martha met with parents of one of the children who had witnessed Clark push the bus out of the water and was concered that they wanted to exploit his gift.
Martha was present while Clark and Jonathan argued in the truck prior to the tornado taking Jonathan's life. Both Clark and Martha stood and watched as the storm carried Jonathan away.
Years later, when Clark came back from searching the globe for the answers he was seeking about his past, she greeted her son with a hug. They both watched as Zod gave his message to the world about delivering Kal-El to them. Later, as Zod threatened Martha on the farm, Clark flew in and attacked Zod and took him across town. The Kent house was damaged, but Martha was able to retrieve the family photo album, and Clark helped her repair the house.
When Clark started to doubt his mission after accusations that Superman's presence raised political concerns, he spoke with Martha about them, who assured Clark that he didn't have to continue as Superman if he didn't want to. Later, Lex Luthor was able to take Martha prisoner to use as a hostage, forcing Superman to confront and kill Batman within an hour or Luthor's mercenaries would kill Martha. However, Martha was saved when Superman begged Batman to "save Martha", the memory of his own mother helping Batman recognize that Superman was still fundamentally human. After Superman's death, Martha oversaw Clark's funeral in Smallville, which was attended by Bruce Wayne and Diana.
After the death of her son, Martha lost track of her payments and the Kent farm was foreclosed on. After a forced move, Martha moved in not far away from an unnamed diner in Metropolis. After Clark was brought back to life, Bruce Wayne bought the bank that now owned her farm and gave it back.
