Peter Cullen and Frank Welker reprise their roles of Optimus Prime and Megatron in the first weekly Transformers TV series since the 1980s.
One of the few Transformers continuities in which Cliffjumper isn't simply a slightly tweaked and red-colored Bumblebee lookalike, but has his own, very distinct design.
The character designers ditched Arcee's classic pink and white color scheme because they thought it would be "too girly" for the cartoon. So they made her blue instead.
Originally, Ironhide was to star in the show instead of Bulkhead, but after the writers realized his portrayal would be better suited for Bulkhead, they replaced the character.
Cliffjumper's design was made to look heftier when the designers were told that Dwayne Johnson would be voicing him.
