Hot Spot leads by example. Whether it's a raging battle or a raging fire, he's right in the thick of things—and that's where he's happiest. While many Autobots get into trouble by not thinking in combat, Hot Spot is a natural warrior who excels at fighting on instinct alone. His fellow Protectobots find his endless energy inspiring (though a bit exhausting), letting Hot Spot command even the most philosophically different of robots like Blades and First Aid as a tight and effective unit. He's a tough fighter to boot—strong, well-armed and well-armored.
His alt-mode is a Blue Mitsubishi Fuso Great Fire Engine.
