Dr. Mashirito and Abale-chan
Oishii Shima no Ū-sama
In this manga, Tech-Tech aliens try to exploit the natural resources of Guruguru island, an island where residents live harmonious lives in a rich natural environment. However, two men from the city decide to protect the pristine island from the evil hands of the Tech-Tech aliens.
- 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 Galactic Frieza Army soldier who resembles a Tech-Tech alien.
