One thing I adore about that two parter.
King Joe was a Zetton level threat, and in any other series, that would have been a huge goddamn deal for the hero. He would have obsessed over it, or commented on how powerful it was, or worried, or even shown the slightest bit of interest that this enemy was stronger, tougher and more powerful than him AND immune to his special attacks.
UltraSeven?
**** that, punch it in the face, then fight it to a stand still for hours.
Seven is hardcore yo.
...that and the drowning of enemies that so much as annoy him.
