The Fantastic Four's flashiest member debuts a brand-new look that resembles a famous anti-hero and former member of Marvel's First Family. While the Avengers are composed of a wide variety of heroes, each with their own unique costume, and the X-Men have gradually distanced themselves from the original five's yellow uniforms, the Fantastic Four have stayed loyal to their original look. The Fantastic Four's iconic blue uniforms are a symbol of their union and shared sense of purpose.
