Machine Man’s enemy Kublai Khan captures the robot and takes him on his blimp. Yes, he’s a criminal who rides in a blimp. Machine Man breaks free and in the process the blimp catches fire and Khan burns to death.
That’s pretty ghastly, especially considering that Steve Ditko only agreed to come back to Marvel if he could draw a character who was unambiguously good. I mean, Machine Man is invulnerable to fire—surely he could have rescued Khan?
I’m lumping #14 in here. Both issues are done-in-ones, and both are pretty bad.
