Diane Moore had two daughters; Sophie in 1991 or 1992, and Jordan, to an unknown man. She raised her daughters under very conservative values, opposing the LGBTQ community and homosexuals as "degenerate sinners". Diane also pushed her children to work hard in order to achieve great things in life.
Diane supported Sophie's marriage to Tyler, approving him as her son-in-law; she praised Tyler's decorated career and appreciated how he always sent her flowers on her birthday. However, Tyler recognized the fact that Diane was a very hard woman.
During the Anti-Monitor Crisis, Diane 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.
Visiting her daughter
The following morning, Diane scolded Sophie for not telling her about her separation from Tyler, wondering why her daughter claimed to no longer love a man the former deemed "perfect". Diane also urged Sophie to find a way to get her job back. However, Sophie declared that she intended to find something she believed in more, taking Batwoman as an example. Diane retorted Batwoman is different from Batman since the vigilante stood for values she didn't recognize, but Sophie knew her mother really disapproved of Batwoman being openly lesbian.
A few days later, after Diane had some coffee, Sophie confessed she was never in love with Tyler, and finally came out to her. Diane asked why she never told her about it before and Sophie replied that it was because she didn't want her to look at her the way she was in that moment. Diane stormed off, angrily asking Sophie how she expected her mother's look of disappointment to be.
Diane later told Jordan what she learned about Sophie, but unlike her mother, Jordan continued to support her sister.
Diane has a severe disdain towards LGBT individuals for no clear reason; other than their sexuality.
