Four Arms is one of the most iconic transformations of Ben Tennyson from the beloved Ben 10 franchise. This powerful alien makes a memorable appearance in the crossover episode “Crossover Nexus” from OK K.O.! Let’s Be Heroes. His striking physical appearance and formidable abilities make him a standout character in this crossover event. Four Arms is a humanoid alien with a robust, muscular physique. He is easily recognizable with his red skin, four green eyes, and two pairs of powerful arms, each with four-fingered hands. His attire consists of a white shirt, black pants, and black gloves, complemented by a vertical black stripe that runs from his back to the front of his body, splitting at his mouth. For fans of both Ben 10 and OK K.O.! Let’s Be Heroes, a fanart cursor featuring Four Arms would be a fantastic addition.
