Create a graphic depicting a whimsical warrior in the style of World of Warcraft. The warrior character has an onion for a head, complete with a visible face, sitting atop a fearsome dragon. He is fully equipped with medieval armor and wears a helmet, fitting the onion shape of his head. In his hands, he holds a shield and a spear. The entire image is designed to look like a vibrant, cartoonish sticker, set against a pure white background to emphasize the sticker style. The dragon adds a majestic yet playful element to the scene
