The phrase denotes a specific product category, combining a fictional character, a type of collectible, and a major retailer. It refers to toy figurines depicting the Marvel Comics character Venom that are sold by the Walmart chain of stores. These items are typically made of plastic and marketed towards children and collectors.
The availability of such products at a large, accessible retailer like Walmart signifies the broad appeal of the character and the profitability of the action figure market. Historically, character-based toys have provided significant revenue streams for both entertainment companies and retail outlets, and this specific example reflects that enduring trend. The price point and accessibility offered by a major retailer expand the customer base beyond dedicated collectors to casual buyers.
