Design a striking hybrid character combining Sonic the Hedgehog and The Flash, blending their iconic features into one cohesive and dynamic design. The character has Sonic's sleek, blue fur with red accents, along with The Flash's signature lightning bolt emblem integrated into the chest. Electric blue and golden lightning streaks radiate from the hybrid, emphasizing incredible speed. The background is a blurred, high-energy environment with streaks of light and motion to showcase velocity. Use ultra-detailed textures and vibrant colors to highlight the fusion of these two legendary speedsters.
