Both "Marvel's Ultimate Spider-Man" and "Marvel's Avengers Assemble" will return to Disney XD with new seasons on 2016, albeit under different titles. As announced by the cable network on Monday, the fourth season of "Ultimate Spider-Man" will be titled "Ultimate Spider-Man vs. The Sinister 6," with the third season of "Avengers Assemble" running under the name "Avengers: Ultron Revolution."

Here's the official description for "Ultimate Spider-Man vs. The Sinister 6," which doesn't specify which characters comprise the "all-new Sinister 6":

In season four of "Marvel's Ultimate Spider-Man vs. The Sinister 6," a confident Spider-Man feels like the ultimate hero after fighting alongside The Avengers and leading a team of heroes at S.H.I.E.L.D. Academy. However, when the wall-crawler discovers that his greatest enemies -- Doctor Octopus, Hydra and the all-new Sinister 6 -- are working together to destroy him and S.H.I.E.L.D., he teams up with a special new team of Spiders, including Miles Morales, Agent Venom, Iron Spider and the mysterious new Scarlet Spider. Spider-Man and his new friends will need to use all of their power to overcome their greatest challenge yet.

"Avengers: Ultron Revolution" looks to have plenty of echoes to Marvel Studios' upcoming slate, with Ant-Man, Black Panther, Captain Marvel and the Inhumans all named as appearing, along with an "all-out Marvel superhero Civil War." Plus, Ms. Marvel -- likely Kamala Khan -- looks to make her animation debut.

In season three of "Marvel's Avengers: Ultron Revolution," the Avengers are not only shocked by the return of a vengeful Ultron, but they also encounter new threats like Baron Zemo, the Masters of Evil, the Inhumans, and the futuristic Kang the Conqueror. It's only with the help of heroes like Black Panther, Captain Marvel, Ant-Man and Ms. Marvel that they have a chance of surviving an all-out Marvel super hero Civil War.

Both series are set to debut sometime in 2016. This is the first name change for "Avengers Assemble;" "Ultimate Spider-Man" is titled "Ultimate Spider-Man: Web Warriors" for its current, third season.
