After Bardock tries to stop an invasion from Frieza to destroy the planet Vegeta, and now fails and dies from Frieza's Supernova, his last words, everything it did, everything is done just to get stronger and protect what is so more important for low-class Saiyan but now is not enough, but before he dies, he fell through to portal and brought him to another dimension/universe, and now Bardock get out the portal and landing in hell for a new life/chance, but Bardock is not only who claim low-class, Imps and Hellhounds from Royalty called low-class who's treating nothing but trash and scum, but now everything changes with Bardock the one Saiyan is gonna prove/defending and help demons low-class to bring hope, stronger and trained to them become warriors with honor and pride, but if someone demons Royaty or not who is gonna way they gonna wish never be born/Existence.
Bardock is to be saying: Will change everything, don't underestimate with Saiyans
