Menasor in the 2015 Transformers: Robots in Disguise animated series is a Decepticon combiner, a massive warrior formed from the merger of five individual Decepticons known as the Stunticons. His body is composed of the team's leader, Motormaster, who forms the torso, with Heatseeker and Slashmark making up the legs, and Wildbreak and Dragstrip forming the arms. While his towering form possesses the combined strength of all its components, harnessing that power is a significant challenge. The five Stunticons have clashing personalities and a low tolerance for one another, which results in Menasor being mentally unstable and his movements poorly coordinated. Rather than focusing on his enemies, Menasor often spends his time shouting orders at his own limbs and belittling them for their incompetence. When he is able to get his components to work together, however, he becomes an nearly unstoppable force of destruction.

In the story, Menasor is formed when the Stunticons aim to demonstrate their power to the Autobot Bee Team. Despite his imposing presence, his first appearance is marred by his lack of coordination when he gets his own sword stuck in the ground, allowing his enemies to escape. He later attacks a human military base, showing his disdain for fighting automated defenses instead of living opponents, and battles the Autobot combiner Ultra Bee. According to Optimus Prime, Menasor's destructive capabilities are so immense that his past crimes include the destruction of an entire planetary system. In a later mission, the Stunticons form Menasor to breach the defenses of a weapons cache on the Moon. After obtaining a powerful plasma thermal accelerator module, Menasor installs it on his arm to use against the Autobots. However, the internal conflict between his components ultimately causes him to freeze up during a critical moment, leading to his defeat and the Stunticons being captured.

The key relationships defining Menasor are those between his five component Stunticons. He is not a separate entity with a unified will, but a volatile gestalt being whose personality is a chaotic mix of his parts. Motormaster, as the torso, seems to exert the most influence, but he is deeply resented by the other Stunticons, which is the primary source of Menasor's constant internal arguments and lack of coordination. The development of Menasor is less about personal growth and more about the fluctuating success of his components cooperating. Initially a terrifying but bumbling threat, his coordination improves when they have a clear objective, such as obtaining the plasma module, making him a more formidable opponent. Ultimately, his inherent instability is his greatest weakness, preventing him from achieving lasting victory. His notable abilities include immense physical strength, the power to wield a large sword, and the capability to integrate powerful weaponry like the plasma thermal accelerator module onto his arm for enhanced attacks.
