|Fifty years have passed since Jack arrived in the future; his sword is missing, he has given up hope of returning to his time, and he is tormented by hallucinations of his parents, his kingdom, and a mysterious figure on horseback. Jack rescues a mother and daughter from several bug robots and defeats Scaramouch, a fast-talking musical robotic assassin (styled after Sammy Davis Jr.) who has destroyed a village to get Jack's attention. Meanwhile, seven young girls are raised and trained from birth to become the Daughters of Aku, a team of elite assassins with the sole purpose of killing Jack.|

- A five-second teaser was released on YouTube the same day of the announcement.
- Artwork used in the teaser derived from the cover of an issue from IDW Publishing's comic book adaptation of the series.
- Work-in-progress excerpts were shared at the 2016 Annecy International Animated Film Festival.
- The new season will have more mature elements and form a cohesive story. The story picks up fifty years after the end of the original series and follows Jack on a journey that will conclude the story of the series.
- The season is set to have 10 episodes.
- Jack is significantly different this season from prior appearances, both in terms of his character design with a shaggy beard and tattered clothes, and in terms of his personality.
- Tartakovsky, at a panel at San Diego Comic-Con 2016, affirmed that the Scotsman will return to the series.
- Due to the passing of Makoto Iwamatsu in 2006, who originally voiced the series' lead villain Aku, Tartakovsky at first considered using a completely different voice for the character. However, considering how Mako's voice was an important element of the character, Tartakovsky stated that he has hired "a guy who does a pretty good imitation; I'll be upfront about it—nobody can replace Mako." Voice actor Greg Baldwin was brought in to mimic the original voice.
- The season was expected to air in 2016, but on October 11, 2016, Chris Reccardi announced on his official Facebook page that the new season will premiere on March 2017. However, there were conflicting reports of that date, as Toonami's showrunner Jason DeMarco has said there was no definite premiere date set. Reccardi later deleted his post.
- Later on, Adult Swim reconfirmed the rumour, in response to a question. The premiere date is set to be in March 11.
- #JackIsBack was used to promote Season 5 of the series.
- Tyler Bates will be providing the music score for this season.
- This season will be co-produced by Williams Street.
- This is the first season that is co-produced by Williams Street despite of Seasons 1 till 4 were co-produced by Cartoon Network Studios.
- In an interview at Comic-Con 2016, it was revealed that Jack will experience killing his first human being in this season.  (1:58)
- This is somewhat contradicting as Jack was show to have already killed three human bounty hunters in the episode "The Princess and the Bounty Hunters".
- It is likely he simply incapacitated them. This can be seen on the absence of blood. And despite being hit by the explosives, it is likely that Boris simply badly injured.
