Bayonetta 2
Madama Khepri is never fully seen in Bayonetta 2, only her fists, feet and shadow can be seen during gameplay. This is mainly due to the fact that she has no complete model in the game. Rosa summons her fists and feet as her wicked weaves but if she is expected to summon Madama Khepri's full body, Madama Butterfly will show up instead.

Book of Infernal Demons
"A goddess of Inferno who controls time and the sun. It is said that she can determine a person's fate by gazing upon the long shadow that forms between their body and the light extending from the land of the dead.
