Holey moley, this might be the best one yet, just with how it escalated.
It almost tells its own story. Teddiursa starts off afraid of being placed into the "evil" Slytherin and tries to warn people about the incoming Lanturn revolution only to become the bad guy who helps usher in the revolution and helps Lanturn beat up all the other Pokemon. A modern day Greek tragedy...
EDIT: my favorite on is DPAN's. Oogie Boogie vibes
