of the character Miles O'Brien in the series Star Trek: The Next
Generation (1987-1994) and Star Trek: Deep Space Nine (1993-1999). In
the Star Trek universe, Keiko Ishikawa is introduced on her wedding
day, about to be married to the character Miles O'Brien. We learn
Keiko Ishikawa is going to be married in the Star Trek: The Next
Generation episode Data's Day which was broadcast on syndicated
television in 1991. Another important episode for Keiko is "Disaster"
(aired 1991) in which she gives birth to her daughter Molly
O'Brien.Keiko and her family is noted as example of how Star Trek was
able to expand its narrative beyond weekly space missions. Keiko and
her family were regularly featured through the entire run of Star
Trek: Deep Space Nine. Although the Deep Space Nine producers wanted
to employ her as a full-time cast member in 1993, Chao could only work
part-time, due to her pregnancy at the time and desire to pursue other
projects.The character has also been included in other Star Trek
media, such as novels.Keiko is played by actress Rosalind Chao. In a
1996 interview with Chicago Tribune, Chao noted how actress Nana
Visitor's real life pregnancy lead to an impact on the plot and
stories of the television show Star Trek: Deep Space Nine. At the time
Chao was playing Keiko on that show, and the writers then established
that Visitor's character, the Bajoran alien Kira Nerys, would be
carrying Keiko and Miles' child. Chao notes that this is one of the
times that real-life events of the cast affected a fictional plot of
the characters on the television show. Keiko O'Brien Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
