Fantastic Four #21 (666)

Synopsis

Val and Franklin are sent back to Earth by their parents, charged with watching N'kalla and Jo-Venn, the warring alien children (Skrull and Kree respectively). Unable to control the children's fighting, the Richardses call for help, and both Wolverine and Spider-Man respond without knowing exactly what the problem is. Believing Alicia to be in danger, Wolverine stabs N'kalla, only recognizing her as a Skrull but not a child. Elsewhere, the presence of the aliens is detected by the Priests of Pama, who believe it is a sign of the coming Dark Harvest.
