Episode: "Imaginationland II” (s11e11)
Original Air Date: October 24, 2007

The younger brother of Ryu's sensei, the demon Akuma, makes a cameo in the evil Imaginationland camp. His dark presence is decidedly more ominous than that of Alien and Shredder, as is his appearance as a hidden boss in Super Street Fighter II: Turbo. The prayer beads around his neck are a diversion; his badass imaginary deeds are the true Akuma. Or he's just a fairly specific fighting game reference. Either one.
