The Unbeatable Squirrel Girl #20

The whole cover is designed as a retro arcade cabinet screen, with a pixelated Squirrel Girl triumphantly perched atop a pyramid of isometric blocks swarming with pixel rats — and a speech bubble full of comic-book censorship symbols suggesting things are not going smoothly. Flanking the screen are real-world peeks at a very confused-looking red-haired girl and a wide-eyed squirrel watching the action unfold, while pixel portraits of a stern woman, a roaring bear, and a blue creature line the side like a villain roster. North, Henderson, and Renzi bring an irresistibly clever video-game energy to this 2017 Marvel gem, making issue #20 one of the most visually inventive entries in the series.
