... Can... Can we talk about the helmet designs for some Tokusatsu Heroes? Because some (Cough cough Ultraman Cough Cough) are weeeeeeeird.
Sure! However, I would like to stress that in universe, the “helmets” on the Ultra Heroes aren’t really helmets, they are their heads. Unlike Kamen Rider or the Sentai heroes, the Ultra Heroes aren’t wearing a costume. Their giant forms are what they really are and their human forms are either a disguise or (as was the case with the original Ultraman) human bodies they have merged with to survive on Earth or keep their human host alive after an accident.
The original character designer, Toru Narita, went through several design ideas including a weird monstrous form called Bemula (a name later used for Ultraman’s first monstrous foe), another called Redman and finally Ultraman. The final design was even based on a space suit and the traditional alien look popularized by stories of alien abductions. You know, the Gray aliens or Roswell crash victims.
So, that’s why Ultraman looks so odd, he’s an alien and was designed to look both heroic and still completely alien. As opposed to Kamen Rider who was designed to look like an insect:
Oh and on a similar note, Tsuburaya never really liked to toss out an idea. One of the earlier names for Ultraman was going to be Woo and that name (like Bemular) was used for one of his foes:
While Redman would later be the name of a certain homicidal killer:
