[Marvel/DC] If Tony Stark had to come up with ways to non-lethally take down the Justice League what methods might he use in comparison to the Batman's approaches?

Whatever the underlying technology, you can be damn sure it would be a ${Hero}Buster suit. All of them would be built out of Adamantium or Vibranium, because enough of the League are planet busters that anything less would fail instantly.

For Superman, he'd probably reverse engineer kryptonite and modify his repulsors to utilize it, and have red solar projectors all over the place.

For Wonder Woman, he'd probably incorporate Asgardian tech, since you're going to need a god's tech to take down a god.

For Flash, he'd probably work up some kind of anti-friction phlebotinum. Or a banana peel.

For Aquaman, he'd create a device that sucks up ambient water vapor.

Tony would need a something like Magneto's helmet to deal with Martian Manhunter's telepathy, and a flamethrower. A really big flame thrower, but still. And some kind of jar for ther esulting protoplasmic goo.

Green Lantern is a difficult one. It's possible Tony would figure out how the battery on Oa transmits energy to the Ring and interrupt that line. He might try to set up some kind of illusion system to distract GL.

Cyborg is another difficult one. Tony would be pretty reliant on JARVIS to fend off Cyborg's hacks, and probably try to install his own virus in Cyborg's programming.

And then there's Batman. This is another tough one, because Tony and Bruce bring a lot of the same advantages to the table, and with the Hellbat, Bruce is going to be able to go toe-to-toe with any armor Tony fields. Tony's best bet would be to hang back and let others wear Bruce down, like Bane did in *Knightfall*, but Tony's ego might very well get in the way of that plan.
