Re: Thor Girl vs Wonder woman vs Mary Marvel vs Supergirl vs Power Girl
I wish it would be Power girl or Mary marvel, but it would probably be Thor Girl. She had enough power to hurt Gladiator, granted he was already down. Also Odin once borrowed power from Thor-girl.
In my opinion, Diana can take any two of them at the same time. Powergirl would be her biggest threat, but we've already seen them bump heads. Diana started dominated the match after realizing that Karen was being controlled.
Thor Girl lost her Designate powers years ago. She's still tough, but I wouldn't give her the win over anyone here one on one honestly. In her prime, though, she would kick everyone's ass.
As is, probably PG or Classic Wonder Woman for the win.
