In the pages of Unbeatable Squirrel Girl, Squirrel Girl has used her power of friendship to reform Spider-Man villain Kraven the Hunter. Kraven has been appearing in recent issues of Amazing Spider-Man as well, and well… from the looks of the newest teaser from Marvel, his goodness may not last.
The teaser, titled Hunted, has Kraven sitting on a throne with antlers and perhaps horns adorning it. He appears to be asking the audience to call him. Behind him are mounted heads of many animal-themed characters, good and bad including White Rabbit, Puma, Scorpion, Lizard, Rhino, Vulture, Beetle, and yes, Spider-Man.

The teaser also lists the apparent creators involved with the "event", current The Amazing Spider-Man writer Nick Spencer and artist Humberto Ramos. It's unclear if this will be a storyline running in Amazing Spider-Man or a separate mini-series or when it will start, but if it follows recent Marvel trends, it might be March 2019.
