Um, obviously the red one was called Rumble after Soundwave partook in the annual San Francisco Rhubarb Crumble eating competition of 1984. He liked this famous dessert so much he coloured his son red and black (he preferred a very well done crumble) and chose to call him 'Rumble, an abbreviation of his favourite treat.
