Mach-3 is a Guardian.
Challenge of the GoBots cartoon
After Cy-Kill's initial failure on Earth with his Zod fleet, Mach-3 and two Guardian Command Centers managed to locate Cy-Kill near Galleon. Mach-3 was seriously injured while fighting against Cy-Kill's Thruster, but Cy-Kill was captured. (Unfortunately, this was all part of Cy-Kill's plan to free his fellow Renegades from the inside of the Prison Moon of GoBotron.)
Mach-3 and Night Ranger encountered the Robo Rebels when they broke free of the Gobotron Stockades to clear their names. Bent Wing and Mach-3 engaged in some dogfighting before the Rebels eluded their pursuers.
"Echoes and Fragments"
As Sideways and Gong played with mingling universal streams, Vec-Tor caught wind of their antics and tracked down Sideways. The Cybertronian attempted to flee the old bot, but instead ran into Mach-3 and Bullet, who apprehended him.
