MJ looks like Starfire in that first page. Also, what's with fictional characters always bragging about how awesome they are when they're in disguise? "He was one of the toughest guys I've ever faced, and he's obviously had hundreds of girlfriends!"
That "gotcha" was amazingly badass, though, I do remember wondering that it could have gone hilariously wrong if all her confirmation attempts had been along the lines of the last one and Peter just had too much on his mind with the whole "Secret identity suddenly known" to think too hard about whether or not an old friend his aunt casually mentioned was retired.
But yeah, you'd think Chameleon would learn to do a little more research before trying to pull off something like this.
