Actually that's not true. During the development of Halo(the RTS)the developers asked Marcus to draw them a futuristic soldier and he came up with Master Chief. Master Chiefs dialogue was based off of Clint Eastwood as they wanted a hero that doesn't talk a lot. The man with no name is technically not true as well. During the development of Halo(the FPS) they couldn't come up with a name for the hero so they called him Master Chief and as time went on they couldn't think of a better name. The armor that the Master Chief wears was almost called Titan but at the last minute they changed it to MJOLNIR. When Bungie was creating the Titan class they wanted a futuristic soldier like the Master Chief. Bungie also got inspiration from the Terminator movies but I don't see the resemblance.
