"Mama, I'm hungry now."
—R.J. to Michonne.[src]

Rick Grimes Jr., nicknamed R.J., is a survivor of the outbreak in AMC's The Walking Dead. He is the son of Rick Grimes and Michonne, the half-brother of the late Carl Grimes and Andre Anthony, and the adoptive brother of Judith Grimes. He resides in Alexandria with his mother and sister.


Season 9

R.J. was conceived shortly before the disappearance of his father and was born 9 months later.

"Who Are You Now?"

Six years after the disappearance of his father, a 5-year-old R.J. is now living with Michonne and Judith in their home in Alexandria.

As Magna sneaks around outside of their house with another knife, she opens a back door slightly but sees Michonne pick up and hug R.J., which prompts her to leave.

Later, after Michonne and Judith's conversation, R.J. runs up to Michonne and asks for food, as she picks him up and hugs him once again.


In Alexandria, R.J. sleeps in his bed as Michonne watches from his bedroom door.


In Alexandria, R.J. plays with Judith and Gracie on the community streets when Michonne comes out of her house and orders Judith to keep her brother safe as she goes over to the guard post. 

At night, R.J. has dinner with his family and watches as his sister leaves.

"The Storm"

In Alexandria, R.J. takes shelter from the storm with the residents in the church. Later, Judith pulls a blanket over herself and her brother to keep them warm, before Gabriel decides they're moving to Aaron's house. They all tie a rope around themselves and head out into the blizzard.

The next day, after the storm is over, R.J. crawls by the snow when Michonne and the others return to Alexandria. He then plays with the group in a snowball fight.
