An AP content from quite an old anime I found a long time ago. I just figured that it isn't posted in this forum yet. From the old Gatchaman series season 2, a little girl is kidnapped into an underwater base of an alien antagonist and is forced to grow into a mutant villian commander in episode 1. The AP effect wears off later in the last episode(52).
AP in episode 1 (4:09-4:29)
AR in episode 52 (20:31-20:49)
P.S.
I was wondering whether I should post this in the Evil Conversion thread in the TF section or in here. The thing is, the girl didn't really turn evil. The antagonist just altered her memories a bit. So I thought that this TF can't really count as an evil conversion, but just more of an AP.
