Today's Fact
Checked against independent sources — the issues are cited below.
For half a century Pietro Maximoff's biography seemed settled: a mutant, son of Magneto, recruited into the Brotherhood in X-Men Vol. 1 #4 (1964). The spell that broke it came in Avengers & X-Men: Axis Vol. 1 #7 (2014), when an inverted Scarlet Witch cursed her own bloodline and the magic tortured Pietro but left Magneto untouched — proof the Master of Magnetism was no blood relative at all.
The explanation arrived in Uncanny Avengers Vol. 2 #4 (2015). Confronted on Counter-Earth, the High Evolutionary told Pietro and Wanda Maximoff that he had taken them as infants from their real parents, Django and Marya Maximoff, experimented on them, and — disappointed with the results — returned them while disguising them as ordinary mutants. Pietro's speed was laboratory work, not an X-gene.
That single reveal rewired everything readers thought they knew: the Brotherhood membership, the mutant underground years, even his House of M losses rested on a classification the Evolutionary had fabricated. Quicksilver spent decades as mutantkind's fastest embarrassment and its fastest defender without ever belonging to it.
Why It's Obscure
A bloodline spell missed the man everyone called his father, and a geneticist's confession finished the job.
