Knuckles retains his personality from Sonic Boom.
In Story Mode
When Sonic and Tails enter Casino Night, he is seen facing Fang the Sniper, but is defeated by the weasel and falls down a cliff. After Sonic defeats Fang, Tails saves Knuckles. He joins the gang to defeat Eggman again. He faces Rogue the Bat in Angel Island and beats her to recover the Master Emerald. He also assists Tails on defeating Bark the Polar Bear when he is brainwashed by Eggman. Knuckles fought Mecha Sonic during the final battle with Eggman along with Blaze, Silver and Manic. He is then quickly knocked unconcious from Dr. Eggman along with Tails and the rest of heros, except for Sonic. Sonic turns into his Super Transformation to fight Eggman's Death Egg robot (if he gets all the Chaos Emeralds). Sonic destroys the robot and Eggman is blow away from the explosion along with Sonic and the heros.
