Little is known about Hummingbird's origins other than one day her mother, an organic food nut, came home and found her husband and daughter eating pancakes. She stabbed her husband 47 times. Hummingbird later set her mother's bed on fire, killing her so that her father wouldn't be lonely. She's a brilliant inventress but makes a point to invent things like cluster bombs and other weapons to cause as much pain, havoc, destruction and death to as many victims as possible. Her latest appearance was as a part of the mercenary group the Fadeaway Man brought together to kill Hawkman.
