>>51352504>Cynthia is in her late 20’s at the least in the games.Here is a small detail, the anime takes a lot of liberties with the ages, Misty, Korrina, Mallow and other characters in the games are teenagers and in the anime they have a similar age to Ash.
I think one of the biggest changes is Lusamine who is in her 40s in the games and it is hinted that thanks to Nihilego's poison she stopped aging, perhaps a nod to the butolin toxin from which botox originates. While in the anime she is a normal mother in her late 20s or early 30s similar to Dhelia, even her younger version of her is a clone of Lillie.
