You know for Red King having such a cool name I was always baffled by both his design and character. I guess I expected more out of him considering his popularity. I liked the way he looked more in this one.
Ultraman was fierce in this too. Really fun episode. I gotta say the latter episodes in the series are what made the show for me and in this is a prime example of what I mean. Love the references to this episode in The Littlest Hero.
