Bloody Mary
Now listen up
She's razor sharp
If you don't get her game
She'll slice you apart
Now she's a cool cool gun
Moves like a cat
If you don't get her game
Well, you might not make it back
She's got the looks that kill
She's bullet proof
She keeps her motor clean
And believe me you
She's a number 13
The clock strikes midnight
She's knocking loud on my door
She's gonna turn on the juice, boy
Then she'll turn up the power
She's got the looks that kill
"Looks that Kill" by Motley Crue
Bloody Mary started out in the ruins of New York, another chick in a booster gang warring against numerous other gangs in the area. She managed to survive an all out assault against her homies, but the rest were killed, leaving her extremely vunerable, so she fled off into the desolate wastelands. Her travels brought her to the R/T and eventually to the sentient suit of armor that became her Mech.
Mary is not accepted by the general populaces of the Mech Tribes, branded a Rogue, an outcast. This makes things difficult, but not impossible. She's allied herself *cough* with Williker and a few other rogues and thus far has managed to be nothing but a pain in the ass for the established Tribes.
