The next solo "Thor" movie in the 'Marvel Cinematic Universe", titled "Thor: Ragnarok", will see the return of Chris Hemsworth as 'Thor' and Tom Hiddleston as 'Loki', on a quest to save 'Asgard' from an apocalyptic event called 'Ragnarok', stoked by the fire demon 'Surtur':
According to other reports, 'Amora' the 'Enchantress' and the executioner 'Scourge' will also appear in the new film, with Enchantress as a love interest for Loki. 'Balder' and 'Beta Ray Bill' will appear and partner with Thor to defeat Surtur.
"...'The Tree of Yggdrasil' will be the start of 'Ragnarok'. Loki may cause Ragnarok by disturbing Surtur the fire demon, and frame Thor by lying to 'Asgardians' to think that Thor had killed his father 'Odin'.
