Solid State Scouter (ソリッドステート・スカウター) is an insert song used in the TV Special Dragon Ball Z: Bardock - The Father of Goku. As this song is heard when Bardock is fighting, it is commonly known as "Bardock's Theme".
Solid State Scouter is performed by the Japanese rock/pop band Tokio. The lyrics and music were written by Fuminori Iwazaki, with arrangement from the Dragon Magic Orchestra.
The name "Solid State Scouter" appears to be a reference to the 1979 album Solid State Survivor by Japanese techno-pop band Yellow Magic Orchestra. The "Tokyo" in the beginning also appears to be sampled from the track "Technopolis" from the Solid State Survivor album.
The song appeared for the first time in a video game in the Japanese versions of Dragon Ball Z: Budokai Tenkaichi 2, and later in Dragon Ball Z: Budokai Tenkaichi 3 for Wii. Another version of this song is featured in the Japanese versions of Dragon Ball: Raging Blast, and Dragon Ball: Raging Blast 2.
In the PAL and USA versions of Dragon Ball Z: Budokai Tenkaichi 2 the song was replaced by Mind Space.
