This is definitely Cool, and they are all Harder, Better, Faster, and Stronger....And the only gender bender that I can see is of the from picture 85-87....and Picture 1-3 is like tranny to me...
Uploader of these are just taking the pictures from a game called Urban Rivals.
The individual character image sets are the images from their evolutions.
The only real Gender Bender, 85-87 involves a character from a "clan" of gifted people (people with superpowers) and his just so happens to be that he turns into a girl when he gets wet.
1-3 is a tranny "evolution"
It is quite a fun game if you enjoy trading card games, and is completely free to play IIRC. However, there is an aspect of pay to win, but every card can be earned for free.
