- Lisa Schaffer - Casting and Voice Director
- This series was originally set in the same reality as Ultimate Spider-Man, designated as Earth-12041. Despite referencing events from previous seasons, and including minor appearances of the Avengers of Earth-12041, Mission: Breakout! appeared to take place in the continuity of the new series Marvel's Spider-Man that premiered in 2017, evidenced by the guest-appearance of that show's version of Spider-Man in "Back in the New York Groove" and "Drive My Carnage."
- After appearing in Ultimate Spider-Man, Marvel's Avengers Assemble and Hulk and the Agents of S.M.A.S.H., the Guardians of the Galaxy sport in this series character designs and personalities similar to their Marvel Cinematic Universe counterparts.
- It is implied that events similar to the Guardians of the Galaxy movie happened this series' continuity as well.
- Ronan the Accuser perishes off-screen in the same way as his MCU counterpart.
- Gamora is stated to have tried to vaporize Quill the first time they met, while she tried to kill him with her blade in the film and Quill is stated to have used his leg jets to blast her away when she did this, as he also did so in the film.
- Ten two-parter short videos were released on iTunes and social media to promote the animated series and show the origin story of each Guardian of the Galaxy (see Videos section below).
- Due to many plot points involving their crossovers with the other Earth-12041 shows, it can be presumed that this show takes place chronologically before the other shows.
- Titus is still a member of the Nova Corps in this show. In Ultimate Spider-Man, he has already been discharged (due to the Guardians) and is implied to have slaughtered all the other Nova, with the exception of Earth's Nova.
- Ronan is stated to have been destroyed by the Guardians, but is revived by Nebula, explaining his presence in Hulk and the Agents of S.M.A.S.H. as one of the final antagonists.
- Similarly to Ronan, the Kree Supreme Intelligence is destroyed in the final episode of Hulk and the Agents of S.M.A.S.H., but is still alive in this show.
- Thor and Loki seem to be on much better terms when discussing the Asgardian-Spartaxian War than they ever have been in the other shows, hinting at Loki's betrayal during this affair being the action that splits them apart for good.
- Also, the Guardians and the Avengers meet for the first time in this show, despite the teams being already aware of each other during their team-up against Galactus in Marvel's Avengers Assemble.
- Thanos has made some appearances in this series, despite getting destroyed in Marvel's Avengers Assemble.
- Six short videos were released on social media to promote the series' second season and show the Guardians of the Galaxy trying to leave Earth after defeat Thanos (see Videos section below).
