The Bully Gets His Day In 'Biff To The Future' #1
In Back to the Future Part II, Marty McFly visits a dystopian timeline where Biff Tannen has taken over Hill Valley, murdered Marty's dad, and married his mom. This turns out to be because his older self in 2015 stole the DeLorean to give his younger self in 1955 a Sports Almanac that enabled him to become wealthy by gambling. But when you think about it, it would take more than results of sporting events for a less-than-brilliant teenage bully to become a wealthy corporate titan.
Biff to the Future, a new six-issue miniseries from IDW, tells that story. Beginning with young Biff receiving the almanac, it follows him as he realizes just what he has and how to use it, and then start accumulating money and power.
