S01E44: Surely, You Jest (2)

Crow manages to regain some ground in his duel against Lazar with his monster, Black Feather Arms Wing, but just then, a purple light shines from the Original Enerdy Reactor within a crater Lazar was investigating, and a black fog starts to envelope Satellite. Whilst Lazar manages to escape, Crow gets caught up in the fog and disappears, along with several Satellite citizens.
