Transformers: Robots In Disguise: All Hail Megatron.

MultToonVerse (Phase 2: Wands and Wings.)

Over three years since both the Autobots and Decepticons crash landed on Earth, three years since Dr. Arkeville's hegemonic attempt to enslave humanity and control their minds to bring doomsday onto Planet Earth... but... three years have passed... and the Decepticons are attacking humanity in a way no one has managed before... with city wide destruction the size of a Godzilla movie, with a human resistance group set on New York to stop Megatron and his forces... as both Autobot and Human Resistances are no more... or so it seems... as the Autobots seek help from Super Hero City, Metropolis, and Gotham City. As the Autobots and their new allies have to stop the Decepticons' new project: Devastator. Six robots that transform into one mechanical giant.
