B-1D4, also going by the names Beewondeefor and the designation The Heart of Steel, was an Imperial droid acquired by Leia Organa in the year 0 ABY. The group was initially unaware that Wondeefor was, in reality, a highly formidable Imperial weapon created by Grand Moff 4-8C. Her special ability was the power to "seduce" any droid throughout the galaxy, and take control of their software, thus forcing them to obey her commands.
