Gisela (Canon)/ZeroTwo64

1="The silver witch, with a liberal nature. She dwells in a barrier where everything moves at high speed, but the witch herself is dull. She unfortunately can not use any sort of scientific power. Her body was once dazzling with silver, but she has tarnished gazing upon the coastal sunset."

2="The silver witch's minion, whose duty is to declare her opinion. She makes a nuisance of herself with the roaring from the pipes extending from her body as she moves about like a freak sandstorm. She hates magnets."

Summary
Gisela is a witch who battles Kyoko during the flashback scene in episode 7 of the Puella Magi Madoka Magica anime. She has a major role in the game Puella Magi Madoka Portable, where she has her own level both in Kyoko and Mami's route. In the anime version of the events, it is assumed that Gisela was defeated by Kyoko in her flashback for the timeline of the anime where Madoka makes her wish to destroy all witches. However, in Madoka Magica Portable, Gisela can be defeated at two different times. One, by Kyoko in her route in the past, to protect her family. Or two, she can be defeated by Mami in her route, during a time period after Madoka has contracted, with or without Madoka's assistance. While Kyoko has an impressive fight against Gisela, the flashback doesn't show the outcome of the battle, making it ambiguous enough to determine with certainty if Kyoko did kill her after all. In the game it is unambiguous as Kyoko kills her in her route.
