Vintage Pulp Movie Poster for Dr. Bizarre

a movie poster for 'Dr. Bizarre in the Multiverse of Sadness' in the style of a vintage pulp cover without any text. The poster should feature a dramatic and surreal scene with Dr. Bizarre, a mysterious figure in a dark, flowing cloak with a striking, enigmatic face, standing in a chaotic multiverse filled with swirling vortexes, strange creatures, and ominous landscapes. Use bold, vibrant colors typical of pulp art, and include exaggerated, dynamic poses and expressions. The overall aesthetic should be gritty, suspenseful, and evocative of classic pulp fiction covers.
