Regressive Baby Powder

The regressive baby powder was a bioweapon that was used by Nanny Nightmare.

Description
The regressive baby powder was developed by Nanny Nightmare sometime before the events of Ben 10. It acts as a bioweapon that targets age, sometimes increasing it, or sometimes decreasing it. The powder is magenta in color.

History
The regressive baby powder was first seen in Growing Pains, where Nanny Nightmare used it on Ben and Gwen, turning them into toddlers, an error in the version that she used. It is latter learned that Nightmare has used the powder on other people, but the amount it was used on is never specified. The powder itself was later used to age Nightmare and her henchmen drastically.
