"Eggman for President" (光をわれらに!,Hikari o Warera ni!!?, lit. "The Light is Ours!") is the forty-first episode of Sonic X, and the second and final episode in the Egg Moon arc.
Everyone tries to stop Sonic's rampage in order to find out why he's doing it. Sonic reveals that the Egg Moon can't possibly block the sunlight all the time, because the Earth is rotating, the Moon is rotating around the Earth, and the two are both revolving around the Sun. If the Egg Moon had really stopped moving, the rotation would allow for sunlight most of the time; therefore, Eggman is lying. Eggman holds the President hostage, but is thwarted when Sonic and co. show up to save him. The Egg Moon is taken out of Eggman's control by Knuckles, and Eggman is sent to jail with Decoe and Bocoe after failing the question of Sonic (Who's the coolest guy around? Me or You?).
