Kimberley Gordon – or 'Flash Gordon', as her dad calls her – was delivered by emergency Caesarean a year ago after her mother Kendra Villanueva was struck in Albuquerque, New Mexico.
But not only did the one-year-old survive the electrical jolt, she now has static hair.
Her dad Ian Gordon said: "Everybody we've seen says it's a miracle she's alive. She's just kind of a play-it-by ear baby."
On July 4 last year, Ian and his 38-weeks-pregnant girlfriend Kendra were watching the Independence Day fireworks when they were hit by a bolt from the blue.
The thunderbolt travelled through Ian's ear before jumping to Kendra's body and leaving through her thumb.

Lt. Ryan Perry of the Albuquerque Fire Department said: "They were both awake and looking at us. They were dazed and confused. But we knew that there were underlying injuries that we possibly couldn't see that we needed to treat quickly and get them to the hospital."
The pair were rushed to the University of New Mexico Hospital, where Kendra was induced and gave birth to little Kimberly. She was two weeks out from her due date.
Two days after that hair-raising strike, Kendra wrote on Facebook: "What a fouth of July got hit with lighting now in the hospital...sucks and i hope my baby is going to start doing better a lot of electricity for a little baby (sic)."
A year on, Kimberly still has neurological damage from the lightning strike. She can't sit up, crawl or digest food properly.
Doctors also don't know when she will begin to walk and talk as the case is so unusual. It is not clear why the her hair is still static.
Kendra said: "It's hard seeing she can't eat like she's supposed to and can't have food yet, just through the [feeding] tube. But other than I'm glad she lived through it all."
However doctors said it was extraordinary that the little girl could survive such a shock.
An emergency medical technician who treated Kendra and Ian said there have only been 11 incidents on record of a pregnant woman getting struck by lightning. Of those, only half of the newborns survived. And there is a 1 in 280,000 chance of being struck by lightning.
Ian said: "Somebody's definitely watching out for us."
He has now dubbed his daughter 'little Flash Gordon' after the 1930s comic book hero. And he hopes his miracle baby 'will run fast, or save the universe'.
