Recently in My Hero Academia (Boku no Hero Academia) the manga by Horikoshi, a character was introduced named Eri. She has the ability to "rewind" people to an earlier state. Unfortunately, she has no control over the intensity of the power (and the villain made sure she didn't get any training).
In her backstory, Eri's power was discovered when she accidentally rewound her father to before he was visible to the naked eye. The panel doesn't show any process, just the pile of clothes where her father used to be.
In the present day, hero Deku uses his powers to continually damage his body so that the Rewind power is occupied undoing that rather than more aggressive age regression. (And then someone who can turn Quirks off by looking at you switches them both off.)
Presumably if the character comes back at a later date, she'll have more control over her power and we might see some proper AR.
