JUSTICE LEAGUE UNLIMITED #14 did its own version of "the Trenchcoat Brigade," even though most of the characters aren't wearing trenchcoats. This version includes Deadman (occupying the body of Wonder Woman in this scene), Doctor Fate, Doctor Occult, Zauriel, Zatanna and Etrigan the Demon. These weirdie-heroes get the lion's share of action while the regular JLU heroes sit things out.
Scene from the debut story of the Little Chief in PEP #40. At least he makes his bones by punching out a mountain lion.
The 1990s MASK cartoon had at least one villain-crossover, the half-hour "Convention of Evil." At least six villains-- Pretorius (Tim Curry), the Stinger (Stuart Pankin), the Tempest (Bud Cort), Lucifer (Jonathan Harris), Kablamus (Jim Cummings) and Gorgonzola the Cheese Witch (Cree Summer) -- had already appeared on earlier episodes, as is illustrated by clips from those shows.
Most of the null-crossovers I've examined here have been covers or one-page interactions of characters that are not genuine narratives, like this one. SECRETS OF HAUNTED HOUSE #44 is a crossover between various horror-hosts, consisting of two pages at the comic's beginning and a full-page joke at the end. Despite the greater length I would still judge this to be a non-narrative vignette of the type I discussed here.
As a curiosity, the letters-page issue of HOUSE also sports a "crossover" of a very different sort, as future comics superstar Todd MacFarlane weighs in with his opinion on a recent issue.
The 1950 Casper cartoon "Once Upon a Rhyme" shows Casper reading a book of Mother Goose tales. From the cover, Mother Goose invites the friendly ghost to enter her domain. He sees the Three Blind Mice (who of course don't see him) but his spectral appearance frightens both The Old Woman Who Lives in the Shoe and Miss Muffet's spider (Miss Muffet having already been scared off her tuffet by said arachnid.) Red Riding Hood isn't put off by Casper's ghostliness, so they become friends, after which Casper's scare potential saves Red from the hungry Wolf.
It's a decent little cartoon, but it's more than a little odd that the pre-adolescent Red looks to be wearing lipstick.
From my review:
______
The only reason Charlie and Vinnie are in "Oldies But Young 'Uns" is to set up the back-door pilot that appeared in the same season a few episodes later, focusing almost entirely on the antics of father and son (with a piddling guest-appearance by Al Bundy). Said pilot was titled "Top of the Heap," the same as the very short-lived sitcom that resulted. "Top" is IMO one of the worst back-door pilots ever made, but it was the only time the makers of MARRIED WITH CHILDREN succeeded in spinning anything off from their one huge sitcom success. Christina Applegate and David Faustino guested on "Top," but the show bottomed out in seven episodes. A retooled version, without any guest appearances, came and went equally quickly.
