Literary Critique of Age Manipulation (others)
Halflife (Marvel) can make people older. Halflife is a bad guy!
Time Master (Marvel) was aging people back in the sixties in Tales to Astonish #63. Time Master is a bad guy. Notice a pattern? Aging someone is the sort of thing a bad guys does. Kind of like (004) Acid Generation!
Age Manipulation was a common DC Silver Age plot gimmick. Batman V1 #119, Flash V1 #157, Jimmy Olsen V1 #66, and Lois Lane V1 #40 have stories about accelerated aging.
Superman wins the prize for being made older (Action Comics V1 #251, Action Comics V1 #270, Action Comics V1 #396).
Supergirl (DC) is turned into adult due to Red Kryptonite and cannot join the Legion of Superheroes in Action Comics V1 #267.
The Silver Age also abounded with stories of characters made younger via one plot device or another (Adventure Comics V1 #317, Batman V1 #147, Jimmy Olsen V1 #66, Adventure Comics V1 #356, Lois Lane V1 #10, Action Comics V1 #284).
Jetta of the 21st Century #7 (Standard) shows the funny side of this superpower.
Professor Enigma (Fantagraphics) again shows this superpower can be comical in Love and Rockets V4 #3.
Kaine Salinger (DC) is the rare superhero that ages people in Outcasts #1.
Jimmy Olsen (DC) fools around with an age accelerator in Superman’s Pal #85 with unfortunate results.
Jimmy Olsen (DC) becomes a baby in for comic effect in Superman’s Pal #54. Jimmy Olsen is supposed to be a funny title although the humor hasn’t aged well. I remember enjoying Jimmy Olsen as a preteen but cannot enjoy the title to the same degree now.
