Hentai is a kanji (compound word) of the words Hen (strange, weird) and Tai (behavior, attitude, appearence etc etc) It is always used to describe a person and NEVER anime or manga) If someone was going to point out anime pornography, they would say "seijin-anime" or "seijin-manga". NOT "hentai"

Seijin (星人, Star-people), which roughly translates 'Alien', are extra-terrestrial beings that originate from their respectively named planets, or are otherwise sentient aliens as opposed to simple Space Kaiju.
In neo-kaiju toys, this generally refers to sentient aliens.

Baltan is definitely my favorite seijin from Ultraman.
