Outsiders 9 & 10, by Winnick and Haley, which features the "new, improved" Sabbac and Captain Marvel Jr. in his "new", WHITE cape. In a nutshell, Timothy Karnes, a character who's never been seen before in the mainstream DC Universe, suddenly becomes Freddy Freeman's foster-brother, makes a pact with the Devil because he's "jealous" of Freddy's being Captain Marvel Jr., and winds up murdered by a Russian mobster for his own powers.

For those who don't know, Junior's supposed to have a RED CAPE, not a white. Freddy's whole "color chart" is supposed to differeciate him from his "big brother", Captain Marvel.
