Sym-Bionic Titan (2010)

S1E15 Disenfranchised

In the episode "Disenfranchised," Lance picks up the guitar and begins to hone his musical skills. Meanwhile, General Steel dispatches a spy to Sherman High, where Octus persuades the spy that a link exists between Titan and the school. During a concert, a dragon-like Mutraddi, previously vanquished by Titan, reemerges as a severed head. However, Illana and Octus cleverly utilize a hologram of the Manus armor to defeat the creature, providing Lance with a credible alibi, as the General is also present at the concert.
