Gold Digger (Gold Digger Vol. 3 #252)

Exploring a set of ruins, Penny and Ace are pulled into a dimensional anomaly. Waking up alone and in an unknown place, Penny is beside herself - literally. As she contemplates her situation, she starts encountering alternate versions of herself, each from a different past. Abruptly, she is at war with herself, as a "Bad Penny" version of her pits her own group of allied Pennys against the "real" one!
