Mark Russell will team up with artist Rick Leonardi for Green Lantern/Huckleberry Hound #1, which sounds reminiscent of the writer's unique blend of history and Hanna-Barbera characters in Exit Stage Left: The Snagglepuss Chronicles. The Green Lantern/Huckleberry Hound mashup will be set during the Vietnam War as veteran John Stewart returns to the United States and has become a member of the Green Lantern Corps. Meanwhile, Huckleberry Hound has been making vocal statements against the war and the public has turned on him. When Huckleberry finds himself caught up in the Civil Rights Movement in Mississippi, Stewart also arrives on the scene and things get complicated.

Sami Basri does the cover, with a variant cover by Yasmine Putri.

In a new twist on the Yogi Bear mythos, there is a spooky spirit bear who lives in Yellowstone Park and he is no longer just stealing picnic baskets. He is also now kidnapping campers. The rangers are forced to hire Deathstroke to take the bear down in Deathstroke/Yogi Bear #1 by Frank Tieri and Mark Texeira.

Tyler Kirkham does the cover, with a variant cover by Paolo Pantalena.

Superman must deal with the dangers of super food in Superman/Top Cat #1 by Dan Didio and Shane Davis. It appears as though there is a new villain who seems to be a sentient pile of... kale? Top Cat and Superman must team-up to stop this new threat, dubbed Kalien.

Shane Davis did the cover, with a variant cover by Emanuela Lupacchino.

Finally, when Dick Grayson visits Hollywood to meet with a movie agent, he discovers that the agent has been murdered and that most of the clues seem to be pointing to the agent's biggest client, Magilla Gorilla. In Nightwing/Magilla Gorilla #1, Heath Corson and Tom Grummett have Dick don his superhero costume and team-up with Magilla to clear his name and track down the real killers.

Marcus To does the cover, with a variant cover by Jonboy Meyers.

All four specials are due out on Oct. 31.
