Fantastic Four - Annual - Vol 1 - #21 - 1988 - Crystal Blue Persuasion! - (VG)

This double-sized annual is a crucial chapter in "The Evolutionary War," Marvel's massive 1988 crossover event that ran across all of its annuals. Written by Steve Englehart during his famously unconventional run on the main title, this issue features the unique, non-traditional "interim" Fantastic Four lineup and leans heavily into Marvel's cosmic and Inhuman mythology.

The High Evolutionary's grand, mad crusade to forcibly evolve the human race reaches the Blue Area of the Moon—home to the hidden Inhuman city of Attilan. Believing the Inhumans' genetically mutated DNA is a threat to his vision of human purity, the High Evolutionary dispatches his heavily armed "Eliminators" to wipe them out.
