CROSSOVER MADNESS

 Since the historical character of Rasputin has IMO acquired what I deem a "legendary" status, I consider that both the 2004 HELLBOY and the graphic novel on which it's based to be charisma-crossovers.

The situation is a little different with characters that are based on myths but who are given some sort of gimmick that doesn't have anything to do with their original stories. For that reason, I don't consider the film's seqjuel GOLDEN ARMY to be a crossover of any kind. However, the 2019 reboot, which mixes at least two figures from disparate mythologies-- Nimue from Arthurian tales, and Baba Yaga from Russian folklore-- does count as a charisma-crossover.

CROSSOVER MADNESS

To celebrate the 50th issue of Warren's VAMPIRELLA in 1976, writer Bill DuBay and various artists collaborated on a crossover-- possibly the first for the vampiric vixen-- between Vampirella and two other characters who had their own serials in the magazine. It's a decent story but not anything I feel the need to review in depth

Here's Vampirella's first meeting with Pantha, the girl with the tendency to go feline and feral.

Later Vampirella and her support-characters encounter the magazine's resident witch-heroine, Fleur.

Finally, because at the time Warren was publishing reprints of Will Eisner's SPIRIT, a final playful story involves a couple of Vampi's buddies visiting Wildwood Cemetery, in the mistaken belief that the long dead Denny Colt may have been revived as a mad killer. More a joke than a real crossover is the last page, where what might be "the spirit of THE SPIRIT" makes an appearance.

 BETTY BOOP AND THE LITTLE KING is a curiosity with nothing much to recommend it but whatever story might lie behind the mundane details of how it came to exist.

 

To be sure, at least Betty is central to the action of this 1936 short, in contrast to her being a glorified guest-star in POPEYE THE SAILOR WITH BETTY BOOP in 1933. Ostensibly the animators made a cartoon sex film in which the sailor-man and the Boopadoop girl got it on, which if extant would probably constitute their most interesting crossover.
