-Carnage goes invsible sneaks up on supes and either sends tendrils into superman's brain to scramble it, or covers his head with symiote to give superman hilucinations, nightmares, making him crazy.
You seriously think that Superman couldn't hear Carnage?
-a big diff between these two, is that superman's not a killer, and carnage goes on killing sprees. while there isn't one tangible thing carnage cares about carnage could score like 30 hostages rapping tendrils around their necks etc....and he would have superman at his mercy.
I thought this was an fair fight...without stupid pedestrians.
-or he can send a symbiotic scream throughout the universe causing hundreds upon thousands of the symbiote species to race their way across space and overwhelm superman with sheer numbers.
Wow, they have to be pretty damn fast, because if they are lightyears away, they need to go to earth fast enought to stop Superman to murder Carnage...by the time they get to earth, Superman is already cleaning the remains of Carnage with an broom.
