Traditional animation (or classical animation, cel animation, hand-drawn animation, or 2D animation) is an animation technique in which each frame is drawn by hand. The technique was the dominant form of animation in cinema until computer animation.
The second season of the spin-off series follows Sonic and the Freedom Fighters after they teamed up with Knuckles who eventually joins the team and defeat Dr. Eggman and Mecha Sonic, but they must face Eggman and some new enemies along the way to wag war against "Robotropolis" to reclaim their kingdom.
