According to ScreenGeek, it was Loki who put Bruce Banner/The Incredible Hulk (Mark Ruffalo) to the gladiator planet which Thor Odinson (Chris Hemsworth) ends up into during the course of the film, setting up a "Planet Hulk" like subplot.

The gladiator fights are contested by the Grandmaster (Jeff Goldblum) as the two Avengers fight each other for his amusement. Valkyrie (Tessa Thompson) will also be present as one of the gladiators in the film and helps Thor and Hulk escape.

The three heroes are set to find the Soul Stone which they will use to save Asgard from Loki and prevent Ragnarok from happening. Hela (Cate Blanchett) helped Loki ubsupr Odin (Anthony Hopkins) from his throne banished him to earth as a homeless man.

However, Hela betrayed Loki and was responsible for releasing the monsters Surtur and Fenris Wolf setting up to destroy the Nine Realms. Hela is accompanied by Skurge, the Executioner (Karl Urban) but will have some sort of moral conflict about her goals.

Loki ends up teaming with Thor and sets to find Odin on Earth with the help of Doctor Stephen Strange (Benedict Cumberbatch). Odin will gain his powers to the climax of the film and fight the Ragnarok beasts.

One major character will meet his demise during "Thor: Ragnarok" as Heimdall (Idris Elba), who is rumored to possess the Soul Stone will die during the film.

Loki will eventually betray Thors and steals the Soul Stone from him as he delivered the Infinity Stone to Thanos (Josh Brolin) as way to save himself from the Mad Titan's wrath, Screenrant reported.

Previous reports teased that Thor and Hulk will eventually meet the Guardians of the Galaxy during "Thor: Ragnarok" since majority of the movie takes place in space and less scenes from earth.

Peter Quill's (Chris Prat) team will return in "Guardians of the Galaxy Vol. 2" next year and will team-up with the Avengers to fight Thanos in "Avengers: Infinity War", even teasing a fight between Hulk and Groot (Vin Diesel).

Thor and Hulk will also reunite with Iron Man (Robert Downey Jr.) and Captain America (Steve Rogers) to reform the Avengers and stop Thanos from obtaining all of the Infinity Stones. Hela is also rumored to return to "Avengers: Infinity War" as the Marvel Cinematic Universe's version of Mistress Death, which Thanos tries to win her affection.
