Create a 6.5-inch action figure of "Octo-Brawler," an octopus-inspired warrior. He has an oversized head with large, expressive eyes and a wide, toothy grin. His muscular body features smooth skin with intricate details, vibrant neon greens, electric blues, and deep purples. Outfit him in mismatched armor adorned with tentacle motifs. His powerful legs combine humanoid and octopus traits, with webbed feet and exaggerated proportions for dynamic poses.
