 Kingdom Hearts 3D: Dream Drop Distance
When Riku is captured by the Black Guards, he is sent to the Light Cycle arena, where CLU pits him against various other Black Guards in a Light Cycle battle. After Riku takes out some of the guards on their Light Cycles, the Commantis appears from above to eliminate him, presumably summoned by CLU. After Riku defeats the Dream Eater on his Light Cycle, it flies off into the sky. Riku blasts a heart-shaped hole in the arena wall and escapes.
Later, when Riku, Sam Flynn, his father Kevin, and Quorra arrive at the Portal, they find CLU waiting for them. He accuses Kevin of breaking his promise that the two of them would change the world together, and he summons the Commantis to demonstrate the applications at his disposal. Kevin is surprised by this, but Riku calmly steps forward and challenges the Dream Eater to battle. Although the Commantis uses CLU's ship to recharge its energy several times, Riku manages to defeat and derezz it.
