The 2021 Free Comic Book Day offerings included issues aimed at young readers. Batman and Robin and Howard (shown) was a DC flip book with Amethyst: Princess of Gemworld—and both ended with cliffhangers. © 2021 DC Dark Horse’s offering also featured two tales: The Legend of Korra (shown) and Avatar: The Last Airbender. The last panel of each of those featured a “The End” notice. © 2021 Viacom International, Inc.
