Notes

• This may be a reference to Marvel's Microverse. Follow the logic: the Microverse was where the superheroic Micronauts hailed from; the Micronauts toyline was an imported version of the Takara toyline Microman; Ga'mede is a Microman mold.
• Our regular-sized region of space is called the "Macroverse".
