Daniel Gillies as Elijah Mikaelson
Claire Holt as Rebekah Mikaelson
Chris Hemsworth as Thor
Charles Michael Davis as Marcel Gerard

The avengers characters won't really appear they will only be mentioned. Mainly Loki and Thor will appear and maybe I'll have Heimdall appear since he has the ability to see anyone and even talk to them from Asgard.
I do not own the originals or any of the characters, all rights go to Julie Plec and co along with CW. Certain events in the story will be altered so they won't exactly be the same as they were in the show.
I do not own Thor or the Avengers or any of the characters, all rights go to the directors of the films and of course the one and only Stan Lee, may he rest in peace. Some events will be altered from the films to fit into the story plot.
