In late 1989 Marvel adjusted their cover dates so that they were only two months ahead of schedule instead of four, hence the "Mid December" cover date. A full month passed between the publication of this issue and the two issues surrounding it.
This issue is a variant of The New Mutants (Marvel, 1983 series) #84.
There exist further variants:
Boom Boom; Cannonball; Mirage; Rictor; Rusty Collins; Sunspot; Warlock; Wolfsbane; Hela (villain); Queen Ula (villain); Vulture (villain); Brightwind; Balder; Karnilla; Warriors Three [Fandral; Hogun; Volstagg]; Eitri; Kindra; Tiwaz; Wolf Prince; Volstagg's children
Boom Boom, Warlock, and the Wolf Prince rescue the Warriors Three. Volstagg's children find Balder and Karnilla. Cannonball, Rictor, Sunspot, and Wolfsbane hide in Hela's army. Hela launches her attack. Meanwhile, the Vulture and Rusty escape from prison.
