'Jack the Jacket Man': 20 Final bosses who shall not let you pass

If you have to pick one final boss to defeat, who's it going to be? 

Video game lovers know the concept of a final boss. After you've traveled through the first part of the level, beating monsters along the way, you get to the biggest, baddest villain of them all. It can take ages to defeat one of these dudes. In some games, the boss will end you dozens of times before you finally win. In others, you have to grind for gear or level up your armor before you ever have a chance at defeating that dude. 

Well, real life has some final bosses, too. I'm a fan of that absolute unit of a blueberry. Not to mention that dude who's holding an utterly ginormous guitar! You can check it out below and select your own final boss to defeat!
