Cover art: Jim Starlin/Joe Sinnott. 

Script: Jim Starlin, Mike Friedrich. 

Art: Jim Starlin/Mike Esposito. 

An issue so important it had a Marvel Milestone Edition reprint made of it! The first-ever appearance of Thanos! Iron Man battles those hemoglobin-loving siblings, the Blood Brothers, while Drax the Destroyer "guides" the Golden Avenger!

Hube's Recommendation: 4 repulsors!
