The Different Story Witches
While a number of witches appear in Puella Magi Madoka Magica: The Different Story, the vast majority of them remain unnamed. Below are images of the various witches that appear throughout the series in order of appearance.
Unnamed Witch 1
The second witch shown and the first witch Kyoko fights. It's presumed this is the same witch Kyoko fails to defeat in Drama CD 3 since the Minotaur Witch uses decoys just like the CD Witch. Kyoko also remarks in the manga how she won't let it get away this time. Her use of a decoy is similar to Charlotte; her true form is her axe.
A group of familiars Mami and Kyoko fight. They don't seem to have a witch.
Unnamed Witch 2
A witch Mami and Kyoko briefly fight.
