Vogler...

In this week's reading of Vogler, we read the sections of "Crossing the 1st threshold," and "Tests, enemies, allies." Our hero is now past accepting the the challenge, and is crossing the 1st threshold. It can be a physically natural barrier with considerably difficult terrain, or a passage guarded by a being, into the new world. But be the challenge either of the two, they truly test the hero's worth of being fit to be on the journey in the first place.
In the tests, they can be of how well the hero judges the beings in the new world or of how he conducts himself for survival in the new, strange world. Allies can be made to lighten the burden of a task, especially if they survive long enough to "defeat the final boss," as us gamers would describe it. Upon acquiring training to defeat the "final boss," heroes often run into characters that are standoffish towards them. Not everyone will like the hero. And some of these standoffish people may become the "final boss" over time, or at least become his/her henchmen.
Personally, the second part of this section is my favorite part of the story. I like seeing the hero develop as he trains himself in whatever way to defeat the evilest of evil creatures. Every story has a different sort of training, it seems, too.
1.) Who's the worst "final boss" and why?
2.) What's the most difficult threshold, and why?
3.) What's the weirdest training you've ever witnessed a hero do, and describe.
