DESCRIPTION: (from Disney XD's press release, June 2015) Disney XD has ordered two new action-packed seasons of the popular animated series on the Marvel programming block - continuing the adventures of Earth's Mightiest Heroes with "Marvel's Avengers: Ultron Revolution" and introducing a new band of villains in "Marvel's Ultimate Spider-Man vs. The Sinister 6." Produced by Marvel Television, both series deliver the biggest, most explosive seasons yet with some of Marvel's most aspirational super heroes facing off against some of the greatest threats in the Marvel Universe. Both of the new seasons are currently in production and slated to premiere in 2016 on Marvel on Disney XD. 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.
