When RoboBorg is approached by the kids for advice on how to better manage their battles, he tells them that they have the power to turn their bikes into Mega Sector Spectra Cycles! Nukus overhears them and has Les create a machine to turn him into Mega Nukus - more evil than ever! Fangula predicts a big battle will happen soon, and that Nukus will reign victorious. When Nukus and Vilor attack and steal the Mega Cycles, the Borgs wonder if Fangula was right!—Anonymous
Nukus and Vilor get an upgrade, going Mega powered. To even things up, the Beetleborgs are given a power-boost by Roboborg, fusing their old powers with their Metallix ones, creating the Mega Spectra Beetleborgs and Mega-Spectra Sector Cycles. But will this added power boost be enough to stop Mega-Nukus.
