Transformers: Regeneration One #88

WAR IN THE CITY! Anarchy reigns on the streets of Iacon as SCORPONOK's grip tightens further, and those AUTOBOTS still willing and able to resist look to their absent leader--who is on an endangered list all of his own. Beneath the surface of CYBERTRON, HOT ROD runs for his life, locked on a collision
course with his maker, PRIMUS!
