!!! He has been killed a few times . The most memorable to me was in the 1986 movie when he asked Galvatron if he was Megatron and Galvie replied ' here's a hint ' , before disintegrating him . In DOTM he met his fate at the hands of a ' fleshling ' - if he could of only seen his own future ... To give a clear answer to the question - Sam killed him with one of Wheeljacks exploding trinkets . Starscream suffers from immortality , he is cursed by it , not convinced ? - recommended viewing : gen 1 episode ' starscream's ghost '
