Lady Mastermind

Fictional character biography
X-Treme X-Men
Regan Wyngarde is one of three daughters of Jason Wyngarde, the original Mastermind. She has an intense hatred for her half-sister, Martinique (though she was the first to use their now-shared codename). She is hated by her sister for "stealing the spotlight", while she hates her sister for being a "skank", with the two of them constantly insulting each other.
Regan is involved in a plot created by Sebastian Shaw to have his revenge against Sage and gain control of the Sydney underworld.

Why this record matters
“Lady Mastermind” is worth following because a concise public description often conceals a longer documentary argument. Here, Lady, Mastermind and fictional provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 7, 2026. The linked authority identifier is Q2028652. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2001.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
