1. Kurtz (Heart Of Darkness)
This one will be the season finale, to set up a big ongoing villain arc for the second season. The League make their way down the Congo River in the Nautilus to stop ivory-trader turned Warlock, the infamous Kurtz. Along with contending with his hoards of fanatical worshippers, once they enter his realm, each member will have to deal with their own personal Horror, because of the Horror Hex hes cast with his warlocking skillz. For Mina, vampires. For Nemo, drowning. For the Invisible Man, being visible. For Quartermain, male pattern baldness. For Jekyll & Hyde,
himselves. There'd be a ton of character development in this episode. I won't spoil the ending of this one though, youll just have to watch it after 20th Century Fox makes it a real thing. One things for sure though, it'll end on a big cliffhanger, and the studio will blow the remainder of the production budget on one big splashy CGI sequence that may or may not involve a Cthulu.
