i like the concept even of its a rip off. my issue is the villain. Arcade? LOL. doesnt have the power or connections to pull this off. Please dont let another Cube or some lame idea that the Grandmaster is behind the scenes really running things and arcade is just here. at least using GM would fit his style and fit the situation but no reason to be behind the scenes. but arcade, did i say LOL yet.
I think what will eventually be revealed here is that, using existing established Marvel Tech (like power inhibiting Nanites) he is using a great deal of Mysterio's old bag of Tricks to appear more powerful than he is. And of course the fairly inexperienced kids just don't know any better.
Arcade has always had an insane ammount of money and there for connections (though it's never quite explained how) I mean he's made murder worlds often enough, without success, so he must be bankrolled somewhere (probably selling less impressive murder tech on the black market to want to be super villains and heroes).
And if you figure he is a bit of a luaghing stock in the villain community, nothing makes people stop laughing quite as much as dead kids. So, in that, one imagines he has a motivation here, to be taken seriously (like so many sociopathic monsters in real life) and it can be assumed he will be taken seriously after this.
I am guessing he will be selling tapes of this to various villain fetishists in the MU as well, which is agian totally his style.
So, yeah, I think this is appropriate for Arcade all told, we're just not used to seeing him successful, though again a lot of that might be that his marks are who they are, and not that he has somehow gotten better at this job.
Really, I highly doubt this will be a "only one walked away" kind of scenerio. I was sad to see Mettle die, but I guess that's the cost of the book, someone real had to die that first issue, and well, he kind of got the short straw there. I figure you'll next see some deaths of the "created for this book" characters (though who knows one of those guys might get to get out. Before everyone realizes that they can fight Arcade in a differnt way.
