- "Well, you've got a bigger responsibility to your family as a father. The boys need to see what a strong and loving and vulnerable man looks like... what your father was to you. You only have them for a short while longer before they go off into the world. You gotta be present."
"I'm trying. I really am. I don't wanna let anybody down. Was it, um... Was it always this hard for you and Dad?"
"Your lives are so much more complicated than ours ever were. Besides, life's a little different in Smallville, remember?"
- —Martha Kent and Clark Kent[src]
In 1979, when Kal-El arrived from the doomed planet of Krypton and landed in Smallville, Martha and Jonathan found his pod; being a kind-hearted couple, they raised the boy as their own son and named him "Clark Kent". Martha and Jonathan taught Clark important lessons and strong moral values as he grew up, which led him deciding to use the extraordinary powers he gained on Earth from its yellow sun to do good, fighting evil and protecting the innocent as Superman.
In 2018, before leaving Earth for more than nine months, Clark did some repairs on the Kent Farm to ensure it was alright for Martha.
During the Anti-Monitor Crisis, Martha as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019, only to be restored a month later, after the Paragons and the Spectre created a new universe.
As a result from the merging of Earth-38 with Earth-1 and Earth-TUD5, the timeline was slightly changed, resulting in Lois and Clark having two sons instead of one, as well as Lex Luthor never being arrested by Superman, and being known worldwide as a beloved and respected humanitarian.
Years later, the Kent family was at a festival at Smallville when Jonathan died suddenly. At the funeral, Martha held Clark's hand as her husband was buried; Clark became emotional and ran from the ceremony.
A year after Jonathan’s death, Clark began questioning his purpose of being sent to Earth, so Martha gave Clark a Crystal they had found with him in the ship. Clark soon left Smallville to discover his destiny.
When Clark decided to become Superman, Martha was supportive and made Clark a special suit that impressed her son so much he bragged its creation to others.
After Clark moved from the farm, Martha noticed that poorer people in Smallville needed help with bills; she went to Smallville Bank and took out a reverse-mortgage to finance the less-fortunate. Martha was also present at Clark's wedding with Lois. When they got pregnant with twins, they went to the farm to tell Martha. Over the years, Martha became ill, so she started being treated by Dr Frye.
In the present, Martha called Clark at Lois and Clark's home but he was not there, so she waited until he called her back; she asked him and his family to come to visit her. The next morning, Martha died of a stroke.
- "Martha Kent was everything this town aspires to be. She was kind, she was generous, and she was always there when you needed her. Everyone in Smallville can remember her sitting right here, talking with and laughing with whoever was right there beside her. And though she is no longer physically with us, her spirit remains, and she will be right here for whoever needs her."

Lana believes that Martha would be happy with Clark living again in Smallville.
After the Harvest Festival, Martha was honored by the citizens of Smallville.
Lara Lor-Van feared that Kal-El would mature without a mother's love when she sent him to Earth; Kal-El told her when he spoke to her consciousness via Lana Lang Cushing that Martha was an excellent mother to him and taught him love.
