Tony DiMera is a fictional character from the Peacock American soap opera Days of Our Lives, played by actor Thaao Penghlis on and off from November 6, 1981, until October 24, 1985, and from July 19, 2007, until April 1, 2009.

Setting up his penthouse with hidden cameras, Tony throws a big party with invites sent to all of Salem's finest.

Learning that the Brady family, the DiMeras sworn enemy, is alive and well in Salem, Stefano has Tony plant roots in the business community in order to continue the vendetta against them.

Reading the diary she learned that Lee was really her mother and that Stefano DiMera was her father, making Tony her half-brother.

Renée quickly broke things off with Tony, not telling him the real reason in order to spare his feelings.

Tony later learned that he and Renée were in fact not related due to a death-bed confession by his mother Daphne DiMera and had the blood tests to prove it.

Kristen travels to the family estate in New Orleans, Maison Blanche, where she is taken captive by a very much alive Stefano forcing John Black to come to the rescue.

In November 1995, Kristen goes to Aremid as her brother Peter Blake is preparing to marry Jennifer Horton (Melissa Reeves).

Anna convinced him to return to Salem to confront his past (and his father), and Tony agreed to team up with the Bradys to end the DiMera/Brady feud once and for all.

There, Kristen blackmails Tony into marrying her — under the disguise of Nicole — in order to gain control of DiMera Enterprises.

In 2020, Charlie Mason from Soaps She Knows placed Tony and André jointly at #28 on a list of the 35 most memorable characters from Days of Our Lives, commenting that "Thaao Penghlis’ lookalike connivers have to share an entry, if only because during any given era, we could never be sure which of them we were really watching.
