Thrustmaster 500 was an upgrade the Zoni could install to Aphelion, when Ratchet found six Zoni. It gave the ship an afterburner enabling it to fly faster. When Ratchet used it the weapon systems could not be used until the Thrustmaster 5000 was stopped. Ratchet had to use the Thrustmaster 500 to bypass the orbital barrier on Terachnos and reach Axiom City.
