Notes
- Some revelations in the main story can be interpreted as applicable to Earth-616 continuity as well.
- The boy that Jarella would have sacrificed herself to save is revealed to have been an illusion created by agents of the Dark Gods to subtly assassinate Jarella and keep Hulk from returning to K'ai. This reality diverges from 616 because the illusion falters before Jarella can act.
- Hank Pym explains that K'ai doesn't actually exist within a single atom, but is rather a parallel world accessed by shrinking beyond the Planck Constant. This helps explain the infinitesimally small likelihood of the Hulk returning to that one particular world every time he's shrunk.
- On their way through various Planck barriers, Hulk and Jarella pass through other "microscopic" worlds from earlier Marvel comics, including the world from Fantastic Four #16, the debris of Hyperion's homeworld, the Microverse of the Micronauts, the world from Incredible Hulk #201, and Psycho-Man's world. Later, these would all be established as different parts of the Microverse.
- K'ai is revealed to be closely linked to the world of the Dark Gods. The Dark Gods recognize Hulk as a threat and try to keep him from K'ai through their agents, Psyklop and Crypto-Man, explaining those villains' involvement in Hulk's various trips to and from K'ai.
