Tank Girl

Tank Girl originally worked as a tank operator and soldier for an ambiguous organization. When the organization gives Tank Girl the task of delivering a ostomy pouching system to a president with bowel problems, her tank gets appropriated and she is unable to make the delivery on time. After this she leaves the organization, and becomes a modern day bushranger, living in her tank and using it to her advantage while finding herself in a number of surreal adventures.  
 
Her preferred weapon is her tank, even in close quarter combat, but also keeps a revolver handy.
 
She did her best to save the world during the 2000 apocalypse, but was more concerned with killing the ones responsible.
