Oh yeah I was worried it might be that one instead of the one I had. Damn. I only have the above ones because I tend to download the comics I already have for stuff like this but I've been unable to track down that newer fight. I believe that was in volume 2 of For tommorow and I only have volume one.
JLA Classified 15.
The last issue of New Maps of Hell
So this alien is screwing with the minds of the entire JLA and has been making every one of them look real bad...
Alien: Are you read for more? (To Superman who's on the ground)
Supes: Actually, I think I'm ready to stop playing with you. (who starts getting up)
Alien: Playing? I've beaten you half to death.
Supes: Not even close. I needed to measure your power and get a handle on what's really happening here. And that took time. So I just soaked up your punches while I worked it all out.
Supes: You see I'm not human. My eyes, for instance, work very diferently. There was a flicker on everything. All the surfaces in here, including yours, cycle 512 times a second. The others would never see that. But I do. Just as I can see and hear all the communications traffic moving around. Finding the frequencies took time.
Supes: I am a scientists son of the House of El. And I am a reporter. And while I may not be as quick at pattern recognition as my wife, I'm not completely stupid. Given time, I can find my way into any story. And this is just a story. Make-believe. You pushed your little stunt just a hair too far, and I saw through it.
Supes: You're strong. Your strategy programming is clever and complex. And you have absolutely no concept of the sanctity of organic life. (Supes then uses heat vision to burn off the aliens right arm.)
Supes: All these things make you a powerful, frightening enemy. But I'm Superman. And everything that's making your stunt work is broadcasting at 18 terahertz. You ever heard white noise at 18 terahertz?
The next pannel is of Supes open mouthed.. and the aliens face melting.. lol
Its illusions fall and it turns out to just be a giant robot.. Superman punches its chest and detonates it.
