The background is solid black, dramatically highlighting the character. The bottom right corner displays the colorful 'Disney PIXAR TOY STORY 3' logo and the North American release date 'June 18, 2010', confirming its official promotional nature. As a core member of the 'Toy Story' franchise, Rex, despite his ferocious T-Rex appearance, is known for his timid, anxious personality and desire to be loved—a beloved contrast. This high-quality 3D rendered wallpaper perfectly captures the character's essence.
