dude i understand gladiator has fought with Thor, but Thor is only capable of 150 mph running speed(his space flight is level 7 speed but he can only run at about 150 mph. Superman can get to speeds of mach 22 in less than seconds on earth, and up to/possibly past light speed once he is out of the atmosphere. His reaction timing is pretty much instant.) With his reaction time none of these guys would see him coming, honestly. He would be dissapearing and re-appearing). These guys don't have the immense superspeed which superman SUPPOSEDLY has , but I don't ever see him using it on the slower characters. If superman's powers were actually used to their potential.. I honestly think HE could win the fight on his own. I've seen ROGUE push back juggy before. For about 500 feet before she threw him through a wall, the force that is supposedly unable to be stopped once moving in a direction. Imagine someone with hundreds of times the strength she has that can move at superspeed could do.. im sure superman could tear through ironmans suit in seconds, and once that thing is out of his heart he is pretty close to dead. Gladiator would be next, and his speed wouldn't be any match for supermans. And imagine his confidence when he jsut saw ironman's suit getting ripped open. Superman would knock him out in seconds. After this he would procede to fight Juggy. It would take him a LONG time to beat him, but I doubt in that possible 20 minutes or so it could take, Juggy would even get one hand on him.
