The Season 4 Boost is a vibrant, cartoonish 3D model featuring a dynamic, flowing energy trail with a gradient color scheme that transitions from electric blue to neon purple. The boost emits a soft glow and has a smooth, polished surface with subtle particle effects that sparkle as it's activated. The shape is sleek and aerodynamic, designed to complement the high-speed action of Rocket League, with asymmetrical fins that add a sense of motion even when stationary.
