Rick and Morty #40 (Oni Press, 2018)

Rick and Morty are locked in a lethal battle royale, but Rick has a secret weapon -- the Transformatron, which can change him into any form. Pizza Rick! Cactus Rick! Butter Churn Rick! IT'S A RICK-STRAVAGNZA! Rick turns into a lot of different things in this issue, okay? There's also a lot of violence and blatant disregard for Morty's well-being! You're gonna love it!
