Blazar is caveman Ultraman, he will rip off body parts, he will scream the Kaiju into stepping back, he will jump up a building and hang like he was King Kong, and just keep screaming and fighting more wildly than normal Ultramen.
That being said, story wise we got...little aside from knowing that Kaijus are a constant threat, Ultraman was already known to exist and...personality wise i guess the captain is one of those that doesn't leave their men behind and...that's it, this has to be a record for least personality given to human characters in the first episode of any Ultraman series.
Like, he's a generic good captain and that's really it, and i guess one of his men is the smart one or the most informed one because fuck me if i can say who the others are, at this point if you put me a photo of everyone, i don't think i could distinguish who the newbie even is.
This was all about showing how humans tend to fight Kaijus and Blazar's first appearance on Earth to fight.
