Good question. I like everybody's different versions of events regarding World's Enemy No 1.
My take is that

is either the daughter of

or the much younger wife of

, and that

was a member of

but had ambitions of his own and so plotted with

to make sure

was indisposed (but not dead) somehow. Then during the events of World's Enemy No 1,

poses as

in order to bring about the downfall of

, and then reveals himself to be

to

. Then when

wakes up after his op

gives him the name

however some time later the real James McCullen decides to infiltrate

and tops

and then becomes

himself.
that way

is still the only person who knows who

and

really are. Coz

reveals his true James McCullen indentity to

as per the Larry Hama GI Joe comics.
That means

is still out there, and plotting revenge against his daughter/ex-wife

and his former
Just as an aside while

has a great origin as per the great text story in BAF Annual 1985 (i think), the origin of

in the GI Joe comics isn't so great. I mean a car salesman, nothing against car salesman but come on.
