- Though the aliens from Dr. Mashirito and Abale-chan look like those in Nekomajin, they are not the same; Akira Toriyama explained in an interview that the aliens he draw generally have this sort of design and, at the time, he enjoyed drawing Nekomajin, so when aliens appeared in Abale-chan, he did not even intend to come up with a new design.
- In the end of Dragon Ball Z: Resurrection ‘F’ 2nd manga chapter there is a Frieza Force soldier who resembles a Tech-Tech alien.
