"Dragon Ball Super" episode 18 and episode 19 officially began the "Resurrection of F" saga that was previously released as an animated film. Episode 20, titled "Warning from Jaco! Freeza and his 1,000 Soldiers are Drawing Near!" will introduce a few new elements to that story by including Goten and Trunks.

In the original film, Goten and Trunks are not included and they do not face off against Freeza following his resurrection and golden transformation. However, the promotional trailer for the episode reveals that the two Saiyan children will learn all about Freeza and may get excited to fight him.

The trailer showcases Jaco, who canonically made his first appearance in a "Dragon Ball Z" related manga as a space patrol man, coming down to Earth to warn the heroes about Freeza's resurrection via the titular Dragon Balls. However, he instead comes across Goten and Trunks.

Previous episodes showed that Bulma did not want the two children from learning about Freeza. Not only was Freeza one of their greatest enemies but it is hinted that she knows the two children might get themselves in danger simply for the thrill of fighting someone who is said to be legendary and powerful.

Other than the inclusion of Goten and Trunks to the main storyline, the trailer also reveals Goku and Vegeta continuing to train. There is a quick scene where Goku senses Vegeta may be able to transform into the Super Saiyan Blue form -- formerly known as Super Saiyan God Super Saiyan transformation.

A few quick scenes in the trailer reveal that Pan will also make an appearance in the episode as well as Goku and Vegeta donning the official Whys uniform. Gohan's new hairstyle will also be seen in the episode, although it is undetermined at this point how long he will be using it before reverting back to his usual hairstyle.

"Dragon Ball Super" episode 20 will release this Nov. 22.
