Un-men

"Un-Man."

As if to confirm the previous post, Donner's captors between them disclose that:

their captive is not American Security so he must be an Un-man, even, as one of them affirms, the Un-man;

but this Un-man, who has made a lot of trouble for the UN's enemies, has been killed several times;

so it seems that the UN has a corps of physically identical "supermen" (p. 37) or, at least, of very able agents who have been disguised to look alike.

(They have not been disguised but that is how it seems to their enemies so far.)

Donner, disclosing nothing to his captors, thinks of the Un-men as "Brothers." (ibid.) We will learn later how they are brothers.

Superhero teams are a major part of superhero mythology so here is a potential sub-series for adaptation to both screen and comic strips. However, within the Psychotechnic History, "Un-Man" remains this single story.
