Age Manipulation

Summary
Age Manipulation is the ability to control the age of things, whether their aging process is accelerated, decelerated, or even reversed. Uses of this ability can be varied, although some examples of this ability in effect are...
 * Rapidly aging a target so that the person ends up being crippled, or even dying from the accelerated aging process.
 * Rapidly reversing the age of a target so that the person's physical state is reversed back to an adolescent, or even rendering them as a helpless child.
 * Rapidly aging a non-biological object so quickly that they literally break down into dust due to decay. This includes the user's surroundings as well.
 * Age Absorption: The user of this ability is capable of absorbing the age of others, causing the user to become younger while the target becomes withered due to rapid aging. Most common applications of this ability is when the user needs to reverse their age in order to maintain a specific appearance/physique, as well as slowing down their aging process.

Limitations

 * Aging Immunity: The ability to be unaffected by the negative effects of aging. Characters with this ability are immune to the physical and mental effects of aging, such as loss of strength, speed, mobility, as well as mental conditions (Senility, memory loss). Thus, users with this ability remain in peak physical and mental condition and are able to perform any sort of skills that may require a character to be younger. This ability may or may not extend to a character's aesthetics, as characters' skin and facial features may give off the appearance that the passing of time has affected this character to a certain extent.
 * The effects of this ability may take some time in order to fully take effect on the intended target.
 * The user may accidentally remove memories/powers of the intended target, or themselves by moving too far in either direction. Potential scenarios of this particular effect coming into play would be:
 * The user/opponent may end up being too young to remember the experiences/techniques that they have fully grasped when in an older state.
