- (acting skills) Bonnie can look like... 10 different people depending on what expression you catch her with? She seems to have an uncanny ability to "change her age". One moment, she can look "9 years old", then the next someone in their early 20s. Then someone who doesn't even LOOK like her. How the heck does she do that? - (Grub)

Power of Shazam!, The
- (AA age forms) Mary Batson was re-introduced in the graphic novel by Jerry Ordway in 1994. An ongoing series followed as Mary Marvel was introduced into the modern DC Universe with a new origin story. #4: When calling upon her powers, Mary is transformed into an adult resembling her late mother (in the same way that Billy resembles his father when in Marvel form).
In the golden age Mary and Billy were twins and Mary did NOT age when she transformed. When Ordway reintroduced Mary he made it that she aged into a woman when she transformed, however, this has not been portrayed consistently by DC EVER. In some instances Mary Marvel is portrayed as a teenager (JLA: World Without Grown-ups) and in the Justice League there was a line saying that Mary is really only 16 (although the age doesn't have to be canon as the character was just trying to point out Mary was under 18) implying that when transformed, she physically looks older (admittedly Mary Marvel was drawn more buxom than Mary Batson, however she still looked pretty young.

transformations
- (rejuv) Once developed (exercises of Kundalini raising, Medusa Effect and beyond) the power of creation may become normal. Some knowledge of magic and words of power and creation are required. Then whatever is imagined will appear in the physical. Spiritual immortality is possible. Physical immortality may also be possible, if the energy flow out of the body can be reversed, eg, so one grows younger at will.

Ella's POV:
I wake up and something feels weird when I get up. I must be imagining it. I get out of bed and for some reason I feel taller and more, well, grown up. It must be my imagination. I get changed and look at myself in the mirror. I almost scream. I'm not 13 anymore. I look at myself. My hair is longer, my hips curvy and I'm all grown up. I know I have a legacy that can change my age but I can't change it above my real age which is 13. I walk to the kitchen.
I sit down as Ella comes down stairs. I gasp in shock as I see her. Marina downs the bowl she was using to make pancakes. We both stare at her, out mouths wide in shock.
Nine's POV:
At first I think that my eyes are playing tricks on me and that this beautiful version of Ella is my imagination. She looks about my age now but that's impossible, isn't it? She couldn't change her age over her real age. Maybe she is getting better at using that legacy. Her looks take my breath away.
Ella?
Marina and I say at the same time.
I think my legacy is getting stronger, I couldn't do this before and now I'm 18. She says. She is my age!
Wow! is all me and Marina can say. She is the most beautiful girl I have ever seen.

Emily closed her eyes and slowed her breathing, her blood flowing through her whilst her body changed, matured itself, getting older fast enough to see the change as it happened, her limbs crawling out and thickening over the bedsheets by the millimeter, her adult self rising if you would... while she slept... Emily grew up.
Her clothing will be rather, er,... strained, because a 13 yr old body wearing child clothes, suddenly growing into an adult body?
... yeah; there will be some tears...
... if you want, you can go ahead and decide the full extent of their ripping and such ^.- ~}

Seems like Emily can't catch a break. She tried on her overalls... too tight, her thighs and bust ripped right through. She tried on Faith's clothes...her toes burst through the shoes and the top could not hold her bust. Now she is trying Tiffany's outfit and still no avail. Even when she willingly shrinks down to being just ten years old, as young as she is willing to go, nothing will fit her for long. She will just grow to adult size again (just don't do it in public Emily!!!)

- (adult AS, rejuv) Exercise One:
Look and Act Younger: Sitting somewhere near the center of a room, close your eyes and "contact" the two upper corners of the room behind you. Then, holding those corners, sit still and don't think. Remain interested only in those two corners.
You can do this for two minutes (minimum) or two hours, always with benefit. No matter what happens, simply hold the corners and don't think.
You can do this daily. It will make you look and act younger.

CEO tests "crazy" genetic therapy on herself, claims it added 20 years of life.

Sadly, and unlike a story on here, the process has stopped and she doesn't look like a teenager or toddler...
The 45-year-old Seattle-area woman, who has no scientific or medical training, underwent the experimental treatment last September in an undisclosed clinic in Colombia. The unorthodox, overseas trial, which was designed to skirt US federal regulations, prompted the resignation of one of the company's scientific advisers. George Martin, of the University of Washington, quit after telling MIT Technology Review, "This is a big problem. I am very upset by what is happening. I would urge lots of preclinical studies." - (Heidegger)

The success of the Transformation Story Archive accounted for a significant portion of the Internet traffic of its non-profit server in Vienna, run by hosting service public netbase/t0. A shift in Austrian politics worked against the site and its host, however. Austrian Freedom Party (FPÖ) leader Jorg Haider, who died under mysterious circumstances, selected "degenerate art" as one target for his party's political capital. By July 1998, this included accusations of the acceptance and facilitation of child pornography against public netbase/t0. The sexual content of the TSA and its age-alteration themes was implicitly included when allegations continued. When the results of these attacks stripped its host of public funding and free access, the TSA hastily relocated to an American server, assisted by several mirror servers.

She's taking different people's favorite old school photos and recreating them in the same space, with the same style of clothes and with the same person, who in most cases, are at least 20 years older than when the first photo was taken. You'll probably be surprised to see how little a person's face changes over the course of their life - link
