Twins Aaron and Griffin Kunitz portray Johnny DiMera
October 23, 2007 (Birth)
Johnny was originally believed to be the son of Lucas Horton, but after the child's birth, E.J. begins to suspect that the fraternal twins might have different fathers because Johnny does not look like his sister. E.J.'s suspicions are correct. They do a second blood test that reveals E.J. to be the father. Johnny's paternal grandfather, Stefano DiMera was pushing to meet his grandson and insisting that E.J. raise Johnny as a DiMera against Sami's wishes. E.J. first resists this notion because he does not want to betray his ex-wife, but since finding out that, Grace was "his" daughter he agrees to raise Johnny as a DiMera against his ex-wife's wishes. Johnny has one older maternal half-brother, William Reed "Will" Horton, twin maternal half-sister, Alice Caroline "Ally" Horton, and one sister, Sydney Anne DiMera. Sami has allowed Johnny to live with his father, Nicole Walker and his grandfather in the DiMera mansion, while under the protection of the federal government as a material witness to a murder. Johnny had cancer in one eye and got it removed and replaced with a glass one.
