"Brave Wars" is the first and only "Brave" series game to be produced for the PlayStation 2. Quantum Leap Layzelber ("Ryoushi Choyaku Layzelber", title can also be interpreted as "Quantum Leap Rayzelver" and "Quantum Leap Rayserver". It is worth noting that "Layzelber" is not counted among the Brave series by Sunrise). Chyota is the partner of an advanced robot called Layzer, who transforms into a Bugatti Chiron and combines with a VTOL jet called the Rayhawk to form Layzelber, who aims to stop the 6 Knights of Varios from conquering the multiverse. Layzelber can also combine with another jet to form Sky Layzelber, a drill tank to form Ground Layzelber, and a high-speed submarine to form Marine Layzelber. Or Layzer can skip the Rayhawk and combine with the other 3 support vehicles to form Dailayzer. Chyota’s rival Gallio has a robot called Emperios that can combine with a racing limousine to form Emperios Forte, who can combine with an armored vehicle to form Emperios Fortissimo. Gallio is aided by his servants Roberto and Fiore. In a nod to Baan Gaan, Layzer is blue and Emperios is red, and the robots are rivals. Layzer’s small support vehicles also function like Baan Gaan’s animals. Both boys’ families each have some scientific skill used to make the robots.
