I just really like these giant alien dudes & their story/conflict with earth

Pretty much.
Giant aliens come to earth to take ownership of it.
They are incredibly advanced and wipe out Earths defenses in hours.
The aliens arrive on a massive mothership space station that homes their entire species. Its HUGE.
They see humans as pests, cheap food, and even novelty pets.
But mainly as vermin like pests. Like bugs.

They have no species name. Not much is known about them.
They are roughly 80 foot tall. With four eyes with vertical slit pupils. Six fingers and toes. With four nose slits on the small mound on their face where the nose would be. & some strange ears that stick out the top of their head.

but that is a very very rough jist of it
& I also do not recommend reading the manga.
Its a gorey graphic rushed ending of Gantz.
Phase3, the ending. Probably could of been its own stand alone story if it was given time & focus.


anyways heres a FA Folder of more giant Gantz aliens:
