Olivier Coipel

Geoff Johns's Avengers run with Olivier Coipel — the Kang Dynasty storyline — is one of the most underrated Avengers arcs of the modern era, a time-travel epic where Kang the Conqueror declares war on Earth from the year 3000 and the Avengers must fight a war spanning multiple time periods simultaneously. Johns used the time-travel framework to bring multiple versions of the Avengers into conflict with each other, and Coipel's detailed, expressive artwork gave the scale of the Kang invasion genuine visual weight.
