A CONVOCATION OF CROSSOVERS PT. 5

 Lsst and sort of least is the LOW CHARISMA crossover. 

I've already mentioned one example of this category in Part 3, that of Wolverine in his first interaction with the X-Men. Having been only a Sub, he had no stature, but he did have a degree of charisma simply from his having fought the Hulk in one story, With the exception of Cyclops, who possessed both stature and charisma by virtue of his long career with the hero-team, all of the other characters were new and only accrued charisma as the original story progressed. Some of the other established X-people appear in the tale as well, but their status is that of "guest stars" rather than functional members of the team-- a point underscored in the next installment, where all the old X's are given their walking papers for the time being. (To be sure, Jean "Marvel Girl"  Grey does get invited back rather quickly,)

NOTE: just after I wrote this, I remembered that Sunfire and Banshee, who were also in the New X-Men, had pretty much the same Sub-status as Wolverine, though the two of them had enjoyed perhaps three or four Sub-appearances apiece. Rather than rewrite the paragraph, take it as a given that what goes for new member Wolverine also goes for new members Sunfire and Banshee-- though Sunfire was quickly disposed of, ending his brush with Prime status almost as quickly as it began.

The same principle applies to the first crossover of the Joker and the Catwoman in BATMAN #2: neither had accrued much charisma at the time of that story, though obviously the writers meant to build up both characters as consequential to the Bat-mythos.

The subject of Subs being nurtured within a particular mythos is relevant to another species of crossover: the old-villain-meets-new-opponent crossover. As I also noted in Part 3, the tag-team villains Mister Hyde and the Cobra had been regular foes of Thor for a short period, and in DAREDEVIL #30, Stan Lee evidently felt that they would be a better fit for Daredevil. In the process of making the transfer, their villain-charisma had to start interacting with the very different charisma of Daredevil.

I should include a parallel to the discussion from Part 4 as to how former Primes might become Subs in another work, but could still enjoy high charisma, as with Dracula's appearance in a Billy the Kid movie. In cases of low charisma, one may have either new or established characters cross over with former Primes for the sake of brief bits of business rather than for major plot-functions. Examples include:

WHO FRAMED ROGER RABBIT? (in which the main characters are Roger and Eddie Valliant)

THE BOOKS OF MAGIC (in which the main character is Tim Hunter, and the vast panoply of the DC Universe exists as background to his decision)

THE STORY OF MANKIND (in which a debate between Satan and "the Spirit of Man" is supported by a bunch of vignettes starring diverse historical figures ranging from Cleopatra to Peter Minuit. (NOTE: though I'm leaving this example in to show where my mind was at back then, I now do not deem it a crossover because none of the historical figures interact with one another, nor with the two debate-happy demiurges.)
