In an effort to maintain a delicate peace treaty, Ben, as Gravattack, faces an unexpected challenge from swarms of tiny alien fleas that have invaded his body. To save the treaty, Rook shrinks down to eliminate the pests before they can cause chaos. However, they soon discover that Poltroon, a Lewodon, deliberately unleashed the fleas on Gravattack to destabilize him, aiming to trigger a meltdown that would incite a war between the Lewodons and Appoplexians and seize control for himself.
