Warlock and Infinity Watch wasn’t a great comic. It wasn’t terrible, but mostly it was just a regular series that didn’t matter–a side series to whatever cosmic event Jim Starlin was writing at the time. But since the purpose of this feature is to give a taste of every appearance of Thanos, it gets time on my blog.
This issue was interesting, though, in that it showed how Thanos “upgraded” Gamora. Still canon–it’s even movie canon.
