Badb wielded a great scythe, and despite the heavy armor she wore, was very agile. She greatly loved Macha, and was furious when Macha died, despite Macha was well satisfied in her demise.
Badb and a number of spider Duendies attacked Shou Ky's house, trapping Shou Ky inside as a bait to get Shura to come. When Shou Ky died protecting Shura, Badb gained immense power from the surrounding jaki, and managed to broke Shura's Kusanagi sword and blinded Shura's left eye. She was defeated when Arima used the power of the Ky to drain all her jaki away.
