With teasers released earlier this week for "Civil War" and moving through "Age of Ultron" vs. "Marvel Zombies" and "Years of Future Past," Marvel Comics has released another mysterious teaser, this time via Newsarama, that proves to be even more head-scratching -- a "Planet Hulk"-type teaser where Captain America and Devil Dinosaur take on a whole army of Hulks.

The series of teasers seem to all reference past Marvel events, and likely have something to do with the "Secret Wars" event by Jonathan Hickman and Esad Ribic announced at New York Comic Con 2014.
