original superman is a punk and even raditz would murk him .. and current superman is probly about ssj2 level and either Goku at the end of Z or GT would smash him worse than Doomsday ...
seriously superman has to be the lamest comic character ever! silver surfer would pwn superman, juggernaut would pwn him, hulk would pwn him, thor would pwn him, galactus would pwn him, spyro would pwn him, mr satan would pwn him, an ice cream truck would pwn him, a fungus would pwn him and the list goes on and on ...
