X303 / T534

T534 or X303 is a 1992 Orion 05.504 bus that first showed up in the Hospital Boarding Arc and is owned by Étienne. It was abandoned by its driver in the fight with Chris when Étienne commandeered it to use against him, which had little or no effect on the outcome of the battle. After defeating Chris, X303 was taken possession of by Étienne. The powertrain of X303 is a Detroit Diesel Series 50 Engine, which Étienne frequently comments on.

Blade of Chaos
X303 played a very minor role in Blade of Chaos, being used infrequently, with its most major accomplishment being the fact that it had been flipped at 80 miles per hour going left and subsequently repaired and restored.
