Game got too big, so there is a probability that Blizzard can actually come after us. So coming forward all characters will look original, but will resemble the characters they were inspired by.
There will be an option in the game to change the names to whatever you want, including, for example, Pharah.
It is still Ana's daughter, though Ana herself is also getting a re-design and a name change. They relationship will remain the same.
We will add an option to freely change any character's name in the settings, but you won't be able to restore the original looks. Sadly, we have to do it for the sake of ensuring that our project won't be struck down by the legal hammer as we grow larger.
It's because of the very noteable fact that we earn money from the game that features characters that do not belong to us. Sure, it should fall under the Parody category, but since we plan a steam release, we are not going to take any chances that may lead up to closing the project due to Blizzard protecting their brand.
