As a callow child, young Sally Blessings was bullied by her classmates, ignored by her teachers, and abused by her parents. "Be grateful for small blessings," the social worker told her. "They must care on some level; at least they got you a yo-yo for Christmas."
She decided to make the world eat
The supervillain Small Blessings has no particular powers, but is possesed of a brilliant, devious mind and a small army of bitter, talented minions. Her signature is that for every terrible act she commits, she gives something back - something small and ironic.
If she burns your house down, she'll send you a gift certificate to a barbeque restaurant.
If she kidnaps you, the cell will be stocked with that great book you always wanted to read but never had time for.
If she sends her minions to set off a bomb in the middle of the annual flamenco dancing competition, they will pause to hand free margaritas to the dazed, injured contestants before they flee the scene in a van with its (stolen) liscence plate clearly visible.
And someday, when she becomes God-Empress of Earth, all will fall on their knees to worship - but young single men will be allowed, indeed, encouraged, to worship a photo of her in her menacing black pointy crown - and nothing else.
